II. Battery Insertion and Replacement
Battery Insertion:
- Turn to detach the lower housing (14).
- Insert one 18500 lithium battery or two AA batteries.
- 18500 lithium battery insertion: Insert one into the left holder with the positive (+) pole upward.
- AA batteries insertion: Insert one into the right holder with the positive (+) pole upward, and then insert another into the left holder with the positive (+) pole upward.
Check battery polarity was inserted correctly. If battery power is sufficient but unable to turn on the transmitter, check the battery polarity.
Power off to conserve battery power. Remove the battery when it will not be used for an extended period of time.
Diagrams on pages 5 and 6 illustrate battery insertion for AA and 18500 lithium batteries.
Cautions during charging:
- Before charging, make sure the inserted battery is an ICR-18500 lithium battery.
- Confirm the battery polarity is inserted correctly.
- Turn off the power first and then charge.
- Do not charge AA batteries or NiMH batteries. Any damage caused by incorrect batteries is excluded from the warranty.
- The charging port doesn't supply power for the device.
- Do not remove the lithium battery during charging status. Detach the charging cable before removing the lithium battery.
- Indicator: Amber (charging); Green (full).
- Check the 18500 lithium battery is inserted correctly if the indicator doesn't glow.
III. Operating Instructions
- Power On/Off:
- Push the power switch (4) upward to turn on. The LCD panel glows when power is on. Push the power switch downward to turn off. (See Fig. 3 and Fig. 4)
- The LCD shows 'OFF...' during power off. (See Fig. 5)
- Press the MODE button (8) to select functions.
- Press the SET button (7), the parameter blinks, press the SET button again to change the parameter. (See Fig. 3)
- Battery Level Status: Replace with a charged battery once the level falls to 10%. The device will power off automatically with an 'OFF' message once the power level falls too low. (See Fig. 6 for battery level indicators)
- How to Prevent from Accidental Power On/Off: To prevent users from powering off the microphone accidentally, switch the Power Switch Block Latch (6) to the left to block the power switch. (See Fig. 7)
IV. LCD and Operating Instructions
- LCD Display. Fig. 7:
- ACT-800H, ACT-240H/ACT-580H: Displays Group/Channel (16), Parameters (17), Battery Status (18), and Audio Signal Level Bar (19).
- ACT-700H/ACT-500H/ACT-300H: Displays Group/Channel (16), Parameters (17), Battery Status (18), and Audio Signal Level Bar (19).
- ACT-800H LCD. Fig. 8: Displays Group-Channel, Frequency, RF Power, Encryption, AF Limiter, Mute Mode, and AF Low-Cut settings.
- ACT-240H / ACT-580H LCD. Fig. 18: Displays GR (Group) – CH (Channel) – ID (ID Code). These are synced from the receiver and cannot be changed on the microphone.
- ACT-700H / ACT-500H / ACT-300H LCD. Fig. 19: Displays Group/Channel and Frequency. For specific channels set via PC, the screen shows only CHANNEL and numbers. (See Fig. 21)
Parameter Settings:
- (A) Group (GRP) / Channel (CH) / Frequency (FREQ.): Synced from the receiver. To change, do it at the receiver and then press ACT button to sync. (See Fig. 9, Fig. 10, Fig. 20)
- (B) AF L-CUT: AF Low-Cut Setting. Fig. 11: Select L-CUT or FLAT. L-CUT: frequency response at 100Hz decreases by 3dB with a slope of -6dB/Octave.
- (C) AF LIMIT: Audio Input Limit Setting. Fig. 12: Select YES or NO. YES: maximum output of the receiver is limited to 1V.
- (D) ENCRYPTION: Display Encryption Information. Fig. 13: The ENCRYPTION function must be set at the receiver first, then using ACT to program the transmitter.
- (E) RF POWER: RF Power Setting. Fig. 14, Fig. 22: Select HIGH (50mW transmitting power) or LOW (10mW transmitting power). Set appropriate power to meet region/country regulations.
- (F) MUTE MODE: Mute Setting. Fig. 15, Fig. 23:
- Select MAN (Manual), AUTO (Automatic), or DIS (Disabled).
- MAN (Manual): Mute function controlled by MUTE button (H). Press MUTE button to mute the transmitter; the Audio Signal Level Bar shows AF MUTE and blinks. Press again to unmute. AF MUTE will be disabled automatically when power off. (See Fig. 16, Fig. 24)
- AUTO (Automatic): Mute button has no effect. Microphone determines MUTE and UNMUTE automatically based on microphone head position (down for mute, up for unmute) or if idle for over 4 seconds (muted).
- DIS (Disabled): Mute is disabled and cannot be muted in any method.
- (G) Error codes:
- ROM-ER → Channel wasn't programmed or internal data error.
- ERROR1 → RF frequency targeting circuitry is failed.
- NO----03 → Set frequency exceeds the upper band. Transmitter frequency will not be changed but can be operated after power cycle.
- NO----04 → Set frequency exceeds the lower band. Transmitter frequency will not be changed but can be operated after power cycle.
- 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 it 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 it can be operated as long as the power switch is turned on again.
- (H) MUTE Button. Fig. 17:
- Press MUTE button to enter MUTE status. The Audio Signal Level Bar shows AF MUTE and blinks. All operations and ACT function are still workable.
- Press MUTE button again to unmute. AF MUTE will be disabled automatically when power off.
- MUTE button is only workable under MAN (Manual Setting) mode.
V. Cautions
- Turn off to save battery life when not in use. Remove the battery if not used for an extended period of time.
- To improve efficiency of transmitting antenna, do not cover the hands over the rear housing section.
- To prevent degraded microphone sound quality, directionality, and annoying feedback, do not cover the hands over the microphone grille.
- Correct posture of holding the handheld microphone is required because the distance between the microphone and the mouth will have a significant impact on the sensitivity and sound quality.
- Keep the microphone grille clean and unblocked to enhance pick-up sound quality.
VI. Notes
- Refer to actual product in the event of product description discrepancy.
- Frequency range, RF output power, and maximum deviation comply with the regulations of different countries.
