The Base and the Remote are paired with each other at the factory
in a process called subscription. If you replace either one, you can
subscribe them as follows:
4.1 Press and hold the Subscription button on the back of the Base.
(Alternatively, you can hold both of the Talk Volume buttons on
the top of the Base down.)
a. The Base Power LED will begin blinking.
4.2 Hold the Remote’s Listen Volume Control in either the up or down
position.
a. The Remote’s Audio Link LED will turn on steadily (no flashing).
The Remote will subscribe to the Base, after which the Base
Power LED will return to the steadily-on state. The Remote’s
Audio Link LED will go out for a few seconds and then begin to
flash once per second, indicating that your CA12CD-S/A is now
ready to use.
Note 4.1: Remotes and Bases from different models and product
generations cannot be mixed. Please see Table 4.1.

1.1 Plug the modular connector on the Console Interface Cable into the
modular jack on the back of the Base. Plug the other end into your
console.
1.2 Plug the AC adapter into a wall outlet, and plug the
power connector into the back of the Base. The
Base Power LED will turn on.
1.3 Slide the battery pack onto the Remote and snap it
into place without forcing it. The CA12CD-S/A will
take a few seconds to select the most reliable radio
channel, and then it will start to blink its Audio Link
LED at once per second, to indicate that it is ready
to use.
1.4 For first-time use, press the Audio Link button to
turn the audio link off, and place the Remote into its
charging well to charge the attached battery pack.
1.5 Place the spare battery pack into its charging well.
1.6 The Charge LEDs will flash until the battery packs
are fully charged, at which time the LEDs will
stop flashing and remain on. (It is okay to use the
Remote after only one hour of charging time if
desired.)
1.7 Press the PTT Button on the Remote to key up your
communications radio. The Talk LED on the Base will turn
onwhenever the PTT button is pressed.

1.7 How to set the PTT button for locking or momentary operation
Locking
Locking operation
When the selector’s slot is aligned with the Remote’s centre-line,
the PTT button can be depressed momentarily or locked in the
ON position by first depressing then sliding the button down
toward the selector until the button locks into place.
Momentary operation
Turning the selector 90 degrees from the locking position will set
the PTT button for momentary operation.
Momentary
2.1 Careful setting of the audio levels, both in your communications
console and in the CA12CD-S/A, is essential for getting good audio
quality and avoiding echo. Please see the separate sheet, Audio
Settings Guide for the CA12CD-S/A, for detailed advice.
2.2 Operating other radio devices, such as DECT cordless handsets,
in the same frequency band as the CA12CD-S/A will reduce the
number of units that can be operated at one time, along with
reducing their maximum range. The CA12CD-S/A operates in the
DECT frequency band (1.88 to 1.90 GHz).
2.3 User 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-S/A.
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
as little as 10 feet. In general, it is best to place them as far apart
from each other as possible.
2.4 Keep mobile phones at least 3 feet from both the Base and the
Remote when the Remote is not near the Base. When the Base and
Remote are near each other, mobile phones can be closer than 3
feet, but should never be placed right next to the Base orRemote.
2.5 Remove the battery pack and power cord from any unused units
to allow more radio spectrum for active units. This is especially
important where large numbers of them are in use.
Battery charging
and management
3.1 A new, fully charged battery pack will last for about 8 hours,
however, we recommend swapping the Remote’s battery pack
with a freshly charged battery pack from the Spare Charger about
every 4 hours. Doing so will help insure that mission-critical
communications are not interrupted by low batteries. Following
this recommendation will also maximise the battery’s service life.
3.2 Between battery swaps, we recommend placing the Remote in
its charging well whenever possible, and, if it is not being used,
turning the audio link off by pressing the Audio Link button.
3.3 If the Remote is left in the charging well with the link up, a new
charging cycle will typically begin about 3 hours after the first
charging cycle. Using the Remote at this time without installing a
freshly charged battery pack could result in reduced talk time.
3.4 A completely depleted battery pack requires about 4 hours to fully
charge.
3.5 The Remote will continue to draw a small amount of power from
the battery even after being turned off. If you need to store the
Remote, remove the battery pack so that it does not become
completely discharged while in storage.
Warning: Touching the battery-charging contacts or placing objects
other than the battery packs and Remote in the charging wells may
adversely affect the operation of the CA12CD-S/A.
Note 3.1: Rechargeable batteries of all types gradually age and lose
their ability to give and receive charge. Over time, this will result in
gradually decreasing talk times. In a typical 24/7 operation, where the
batteries are regularly being charged and discharged, werecommend
that you monitor their performance and replace them as needed.
