5. Functions and Operation

5-1. Bed Call (BED No.: 4 digits)

To initiate a call from a bed unit or answer a call:

• Using Handset: Pick up receiver -> Input sick room and BED number -> Press Call (#) -> Talk.
• Using Handset (Shortcut): Pick up receiver -> Press Shortcut button -> Talk.
• Using Speaker Phone: Input sick room and BED number -> Press Call (#) -> Talk.
• Using Speaker Phone (Shortcut): Press Shortcut button -> Talk.
• Alternative: Press Shortcut button -> Pick up receiver -> Talk.

When conversation ends, hang up the handset. During conversation, a green LED will be lit, and the display will show "Call xxxx-Bed No".

5-2. Sub Station Function

For communication between master and sub-stations:

• Press the call button on the sub-station to communicate with the master station. The green lamp on the sub-station and the white lamp in the corridor will light up. The master station's LED will indicate an alarm.
• Press the cancel switch on the sub-station to cancel communication (master station LED displays "Sub cancel REQ").

Lifting the handset on the master station initiates communication (Corridor Light turns off). If the master station is in use, the bed's green LED will flash for its conversation. Pressing the call button reserves the call, indicated by a red lamp, and connects automatically after the current conversation ends.

5-4. Presence Switch

Used by nurses to indicate their location via the corridor lamp, signaling a response to the master station's call. When the presence switch is active, the corridor lamp displays the master station's status. Pressing the switch again cancels the presence status. Under presence status, calls are treated as STAFF CALL. When a nurse enters a patient room, pressing the presence switch turns on the white corridor lamp; pressing it upon exiting turns off the green LED, canceling the presence.

5-5. Emergency Switch (For toilet use)

Push the switch to announce an emergency. The corridor lamp will light up, and the master station will display a red lamp. Pressing the switch again cancels the emergency.

5-6. Emergency Shower Switch (For shower room use)

Push the switch to announce an emergency. The corridor lamp will light up, and the master station will display a red lamp. Pressing the switch again cancels the emergency.

5-7. Staff Call Function

In an emergency, a nurse in a patient room can announce it to the nurse station via the call button on the sub-station. If a presence switch is active, the white corridor lamp lights up, and the red corridor lamp blinks. Pressing the off switch cancels the presence. Conversation is possible when the master station receives the call, indicating the presence location.

5-8. Emergency Switch (Corridor Toilet)

Push the switch to announce an emergency; it can connect up to 16 units to the master station. The corridor lamp will light up, and the master station will display a red lamp. The master station will alarm directly, and the red LED in the corridor toilet will blink. Pressing the emergency switch again cancels the function.

5-9. Interphone Call

Interphone calls can be made to other locations or nurse stations by installing additional interphones or between master stations. Lift the handset, press the Interphone button, and dial the room or Interphone number. You will hear a busy tone or back tone if the line is busy or receiving.

When the receiver answers, communication is possible. To cancel, hang up the handset; if the receiver cancels, you will hear a busy tone.

5-10. Interphone Receiving

When one interphone calls another, a call sign rings and displays the interphone number. Lift the handset to communicate. If you are on a BED phone, the Interphone LED and communication sign will blink. If you hang up, the interphone call will ring, allowing you to answer.

5-11. Interphone Broadcasting

To broadcast, lift the handset, press the Interphone button, and dial '00'. All master stations and interphones will receive the broadcast. Master stations currently on a BED phone cannot receive broadcasts.

5-12. Speaker Phone

You can call a BED or Interphone without lifting the handset. Receiving is possible, but communication requires using the handset. Press the speaker phone button to call a BED directly using the BED No. or dial button. You can also call a master station or interphone by pressing the speaker phone button and then the dial button.

5-13. State & Time Display

The master station's LCD continuously displays the year, month, day, and time. To set these, use the adjustment buttons for time, year, month, day, time, and day of the week (Sun=0 to Sat=6), then press the Input button.

6. How to assign the common Number

This system uses micro-process-based data communication, requiring identification number setup for communication functions.

6-1. Interphone

Interphone numbers are assigned using DIP switches located at the bottom of the CDS-90AN. The available identification number range is 10-99.

Example: No.43 can receive interphone broadcasts (1+2+8+32=43). No.90 cannot receive interphone broadcasts (2+8+16+64=90).

DIP Switch Configuration Diagram Description: A diagram shows DIP switches labeled 1 through 8, with ON/OFF positions. A legend indicates: 'P' for Reject switch for receiving the Interphone broadcast, '64' for Switch (Interphone No.64), and '1' for Switch (Interphone No.1).

7. Bed Programming

The system can be programmed after the DIP switches are completely set. Programming is only available in the waiting (Standby) position. The system should not be operated during programming. Testing involves paging from the bed (refer to drawing no.9-4). After completion, the system is ready for communication.

7-1. Bed No. and Induction Lamp

• Press the mode button; "password" will blink on the display.
• Enter the password (9999); "Program" will blink.
• Enter the code (00); "Pr00[0000]" will blink.
• Use the arrow button to display "pr01[0000]".
• "Pr02" indicates the bed number, which can be set up to No. 32.
• Pressing the call button from the bed to communicate with the master station will display "CALL>XXXX-XX". Lift the handset to input the bed number. Pressing the remote-control button shows the following:

Operation Examples:

• No.43 unit available to receive broadcasting: DIP switches 1, 2, 8, and 32 are ON (summing to 43).
• No.90 unit impossible to receive broadcasting: DIP switches 2, 8, 16, and 64 are ON (summing to 90).

Button Functions:

• Pressing "1" button: "ADDR>XXXX-XX" blinks; input number and press remote-control button.
• Pressing "2" button: "GROUP>-XX" blinks; input number and press remote-control button.
• Pressing "3" button: "LAMP>-XX" blinks; input number and press remote-control button.
• (No.1: Bed no., No.2: Special Group like Surgery, Labor, etc., No.3: Induction lamp Group).

7-2. Input DSS number

With DIP switch No.2 ON and under speaker phone status, press the room No. and BED button for over 1 second to input the DDS No. after finishing speaker phone status. For numbers greater than 49, press the speaker phone button, DSS button, room No., and BED button, then press the remote-control button. Ensure DIP switch No.2 is turned OFF after this process is complete.
