1.1 Operating other devices in the same frequency band as the

CA12CD/A 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/A
operates in the DECT™ frequency band (1.88 to 1.90 GHz).
Various versions of the CA12CD/A are available for use in
specific countries.

1.2

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/A.

In low-density installations (e.g. 5 units placed 3 metres

apart), the range can be greater than 3 metres. In high­density installations (e.g. 30 units placed 45.7 centimetres
apart), the range could decrease to 3 metres.

1.3

Plug 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.

1.4

Plug 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.

1.5

Slide 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.

1.6

Attach a headset to the remote unit.

1.7

Place CA12CD/As at least 30.5 centimetres away from

CRT-type computer monitors.

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.

2.6

A fully charged battery pack will last for up to eight hours.

2.7

To maximise 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.

2.8

A 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/A.
