2Battery Charging
& Management
2.1 To attach the Battery Pack to the Remote Unit, simply slide the Battery Pack onto the Remote Unit and snap it into place. Do not force them together.
2.2 The Base Unit is equipped with two battery-charging wells. The larger well allows charging of the battery while it is attached to the Remote Unit. The smaller well allows charging of a spare Battery Pack all by itself.
2.3 Insert the Remote Unit and the spare Battery Pack into their respective charging wells. The Charging Indicators will flash while the Battery Packs are charging.
2.4 When a Battery Pack is charged, its Charging Indicator will stop blinking and glow steadily.
2.5 The On-Off Indicator on the Remote Unit will begin to flash as soon as the unit is ready for use. This may require about 45 seconds while the Remote Unit determines and selects the most reliable radio channel.
3Operation
3.1To maximize user density, always turn the Remote Unit off when not in use.
3.2Press the On-Off Button located on top of the Remote Unit. The green On-Off Indicator will begin to flash. If the battery has just been installed, the Remote Unit will automatically turn on and the On-Off Indicator will begin to flash. This may require about 45 seconds. (Reference Section 1.5)
3.3Depressing the Push-To-Talk (PTT) Button on the Remote Unit will generate the “key” signal to your console or radio. While the PTT Button is depressed, the green Talk Indicator on the Base Unit will illuminate.
3.4The operation of the PTT Button can be adjusted with a
screwdriver to be either lockable or non-lockable as shown.

1.1Operating other devices in the same frequency band as the CA12CD will reduce user density and range. In North America, the CA12CD operates in the UPCS frequency band (1.92 to 1.93 GHz). In other regions, the CA12CD operates in the DECT frequency band (1.88 to 1.90 GHz). Various versions of the CA12CD are available for use in specific countries.
1.2User density and range can vary widely due to such variables as building layout and whether other devices are operating in the same frequency band as the CA12CD.
In low-density installations (e.g., 5 units placed 10 feet apart), the range can be greater than 100 feet. In high-density installations (e.g., 30 units placed 18 inches apart), the range could decrease to 10 feet.
1.3Plug the modular connector on the Console Interface Cable into the modular jack on the back of the Base Unit. Plug the other end into your console.
1.4Plug the AC Adapter into the wall outlet, and plug the round power connector into the back of the Base Unit. The Base Power Indicator will illuminate.
1.5Slide the Battery Pack onto the Remote Unit. When the Battery Pack is installed or changed, the On-Off Indicator will begin to flash slowly as soon as the unit is ready for use. This may require about 45 seconds while the Remote Unit determines and selects the most reliable radio channel.
1.6Attach a headset to the Remote Unit.
1.7Place CA12CDs at least 12 inches away from CRT-type computer monitors.
2.6A fully charged Battery Pack will last for up to eight hours.
2.7To maximize the life of the Battery Pack, turn the Remote Unit off and place it into the charging well when not in use. Prior to being used, Battery Packs must be charged for at least one hour or until the Charging Indicator changes from blinking to continuously on.
2.8A completely depleted battery requires three hours to fully charge.
Note: Always release (disengage) the PTT Button before swapping Battery Packs.
Warning: Touching the battery-charging contacts or placing objects other than the Battery Packs and Remote Unit in the charging wells may adversely affect the operation of the CA12CD.

How to select the lockable or nonlockable switch position
Lockable Position
Note that the selector slot is aligned vertically. The Push-to-Talk Button can be depressed momentarily or locked in the ON position by first depressing then sliding the button until it locks.
Nonlockable Position
Turn the selector horizontally. The Push- to-Talk Button can be depressed momentarily when you wish to speak.
3.5To get the best audio performance from your CA12CD, please use the guidelines on the separate card, Setting Model CA12CD Audio Levels. Properly-adjusted audio levels are especially important for avoiding sidetone echo, as well as for being able to hear your callers and be heard clearly by them.
3.6The Base Unit and the Remote Unit are paired with each other at the factory in a process called subscription. If you replace your Remote Unit, or if your Remote Unit loses its subscription (shown by a rapidly flashing On-Off Indicator), you can perform the subscription process as follows:
•Hold both of the Talk (Sending) Fine-Adjust Volume Controls on the top of the Base Unit down.
•The Base Power Indicator will begin blinking.
•Hold the Remote Unit’s Listen (Receiving) Fine-Adjust Volume Control in either the up or down position.
• The Remote Unit’s On-Off Indicator will turn on steadily (no flashing).
•The Remote Unit will subscribe to the Base Unit, after which the Base Power Indicator will return to the steadily on state. The Remote Unit’s On-Off Indicator will go out for a few seconds and then begin to flash slowly. Your CA12CD is now ready to use.
