II. Battery Insertion and Replacement
1. Battery Insertion (Fig. 2)
Diagrams illustrate the correct insertion of AA batteries and an 18500 lithium battery into the battery compartment, showing polarity (+/-) and orientation. To insert batteries:
- Turn to detach the lower housing (14).
- Insert one 18500 lithium battery or two AA batteries.
- For 18500 lithium battery: insert with the + pole upward into the left holder.
- For AA batteries: insert one into the right holder with the - pole upward, and then insert another into the left holder with the + pole upward.
Ensure battery polarity is correct; otherwise, the transmitter may not turn on even with sufficient battery power.
Power off the device to conserve battery power. Remove batteries when not in use for extended periods.
4. Charging via USB Type-C
This device can charge only one ICR-18500 lithium battery via USB Type-C. Cautions during charging:
- Ensure the inserted battery is an ICR-18500 lithium battery.
- Confirm battery polarity is inserted correctly.
- Turn off the power before charging.
- Do not charge AA or NiMH batteries. Damage from incorrect batteries is not covered by warranty.
- The charging port does not supply power to the device.
- Do not remove the lithium battery during charging. Detach the charging cable before removing the battery.
- Charging Indicator: ? Amber (charging); ? Green (full).
- If the indicator does not glow, check if the 18500 lithium battery is inserted correctly.
III. Operating Instructions
1. Power On/Off
Push the power switch upward to turn on. The LCD panel glows when power is on. Push the power switch downward to turn off. Figures 3 and 4 show examples of the LCD panel displaying 'GRP - CH 01 - 01' and 'GR-CH-ID A 02-03', along with the SET, MODE, and Power buttons.
Figure 5 shows the LCD displaying 'OFF...' indicating the device is powering off.
2. Select Functions
Press the MODE button to select functions.
3. Change Parameters
Press the SET button; the parameter blinks. Press SET again to change the parameter.
4. Battery Level Status
Replace the battery when the level falls to 10%. The device will power off automatically with an "OFF" message when the power level is too low. Figure 6 displays battery level indicator icons showing full (100%), 80%, 60%, 40%, 20%, and low (10%) charge levels.
5. Prevent Accidental Power On/Off (ACT-800H / ACT-700H only)
To prevent accidental power off, switch the Power Switch Block Latch (6) to the left to block the power switch. Figure 7 illustrates the Power Switch Block Latch in its normal position and in the locked position.
IV. LCD and Operating Instructions
1. LCD Display (Fig. 8)
Figure 8 shows examples of LCD displays for different MIPRO ACT series models. The LCD displays various information indicated by numbers:
- 16 Functions
- 17 Parameters
- 18 Battery Status
- 19 Audio Signal Level Bar
2. ACT-800H LCD (Fig. 9)
Figure 9 details the ACT-800H LCD display elements, which include:
- (Group-Channel) (Frequency) (AF Low-Cut) (AF Limiter)
- (Mute Mode) (RF Power) (Encryption)
(A) Group (GRP) / Channel (CH) / Frequency (FREQ.) (Fig. 10)
Figure 10 illustrates the 'GROUP / CHANNEL' and 'FREQUENCY' displays. Group / Channel / Frequency are synced from the receiver and cannot be changed on the transmitter. To change these settings, adjust them on the receiver and then press the ACT button to sync.
Regulatory frequency bands: NCC: 510~530MHz / 748~758MHz; FCC: 470~608MHz; CE: 470~789MHz / 823~832MHz.
(4) PC-set Channels
Figure 11 shows that when specific channels are set via PC, the screen displays only CHANNEL and numbers, e.g., 'GRP - CH * * - * *'.
(B) AF L-CUT: AF Low-Cut Setting (Fig. 12)
Figure 12 shows the AF L-CUT setting options. Select L-CUT or FLAT. L-CUT reduces frequency response at 100Hz by approximately 3dB with a slope of -6dB/Octave.
(C) AF LIMIT: Audio Input Limit Setting (Fig. 13)
Figure 13 shows the AF LIMIT setting options. Select YES or NO. YES limits the maximum output of the receiver to 1V.
(D) ENCRYPTION: Display Encryption Information (Fig. 14)
Figure 14 shows the ENCRYPT setting display ('ENCRYPT NO'). The ENCRYPTION function must be set on the receiver first, then use ACT to program the transmitter.
(E) RF POWER: RF Power Setting (Fig. 15)
Figure 15 shows the RF POWER setting options. Select HIGH or LOW. HIGH provides 50mW transmitting power, and LOW provides 10mW. Set appropriate power to meet region/country regulations.
(F) MUTE MODE: Mute Setting (Fig. 16)
Figure 16 shows the MUTE MODE setting options. Select MAN, AUTO, or DIS.
- MAN (Manual): Mute function is controlled by the MUTE button. Figure 17 illustrates this, showing the LCD displaying 'AF MUTE' blinking when muted. Press the MUTE button again to unmute. AF MUTE is disabled automatically on power off.
- AUTO (Automatic): The mute button has no effect. The transmitter mutes/unmutes automatically based on microphone orientation (down = mute, up = unmute) or if idle for over 4 seconds.
- DIS (Disabled): Mute is disabled and cannot be muted.
(G) Error Codes
The following error codes may appear:
- ROM-ER → Channel not programmed or internal data error.
- ERROR1 → RF frequency targeting circuitry failed.
- NO----03 → Set frequency exceeds the upper band. The transmitter frequency will not change but can be operated as long as the power switch is turned on again.
- NO----04 → Set frequency exceeds the lower band. The transmitter frequency will not change but can be operated as long as the power switch is turned on again.
3. ACT-240H / ACT-580H LCD (Fig. 19)
Figure 19 shows the ACT-240H / ACT-580H LCD displaying GR (Group) – CH (Channel) – ID (ID Code). These messages are displayed only and cannot be changed on the transmitter. To change Group / Channel / ID Code, adjust them on the receiver and press the ACT button to sync.
- ACT-240H: GROUP A, CH 1~12, ID 1~64.
- ACT-580H: GROUP A, B1, B2, CH 1~12, ID 1~64, and P pairing mode.
4. ACT-700H / ACT-500H / ACT-300H LCD (Fig. 20)
Figure 20 provides an overview of the ACT-700H / ACT-500H / ACT-300H LCD display elements, which include (Group/Channel) (Frequency) (RF Power) (Mute Mode).
(A) Group (GRP) / Channel (CH) / Frequency (FREQ.) (Fig. 21)
Figure 21 illustrates the 'GROUP / CHANNEL' and 'FREQUENCY' displays. Group / Channel / Frequency messages are displayed only and cannot be changed. To change, adjust on the receiver and press ACT button to sync.
Regulatory frequency bands: NCC: 510~530MHz / 748~758MHz; FCC: 470~608MHz; CE: 470~789MHz / 823~832MHz.
(4) PC-set Channels (Fig. 22)
Figure 22 shows that for specific channels set via PC, the screen displays only CHANNEL and numbers.
(B) RF POWER Setting (Fig. 23)
Figure 23 shows the RF POWER setting options. Select RF-HI or RF-LOW.
(C) MUTE MODE Setting (Fig. 24)
Figure 24 shows the MUTE MODE setting options. Select MANUAL or DISABLE. MANUAL uses the MUTE button to mute/unmute. DISABLE means the MUTE button is disabled.
(D) Error Codes
The following error codes may appear:
- ERR no01 → EEPROM Channel wasn't programmed or internal data error.
- ERR no02 → For testing only.
- ERR no03 → The set frequency exceeds the upper band. The transmitter frequency will not be changed but can be operated as long as the power switch is turned on again.
- ERR no04 → The set frequency exceeds the lower band. The transmitter frequency will not be changed but can be operated as long as the power switch is turned on again.
(E) MUTE Button (Fig. 25)
Figure 25 illustrates MUTE button operation. Press MUTE button to enter mute status (AF INPUT MUTE). Press MODE, SET buttons to select parameters. Idle for 5 seconds and return to MUTE mode. Press MUTE button again to unmute (AF INPUT UNMUTE). Unmute Mode shows UNMUTE for 1 second and returns to Home Screen. MUTE button is only workable under MANUAL mode.
V. Cautions
- Turn off to save battery life when not in use. Remove batteries for extended periods of non-use.
- To improve transmitting antenna efficiency, do not cover the rear housing section with hands.
- To prevent degraded sound quality, directionality, and feedback, do not cover the microphone grille with hands.
- Correct posture for holding the microphone is required, as distance from the mouth significantly impacts sensitivity and sound quality.
- Keep the microphone grille clean and unblocked to enhance pick-up sound quality.
VI. Notes
- Refer to the actual product in case of discrepancies with product descriptions.
- Frequency range, RF output power, and maximum deviation comply with regulations of different countries.
