Optional NiMH Rechargeable Battery Pack (BT126)
NOTE:
If using the optional rechargeable battery pack BT126, review and become
familiar with the rechargeable battery charger manual prior to use.
The rechargeable battery pack BT126 is a sealed battery pack that has no user-
serviceable components within the battery pack.
Fig. 7: BT126 Battery Pack
The rechargeable battery pack BT126 is shipped from the factory with a minimal charge
and will need to be charged prior to use for the first time with the specified charger.
NOTE:
When using the optional tether mode on the CHTX transmitter, the battery
packs will not be recharged from the tether power feed. The rechargeable battery pack
only can be recharged using the specified charger.
When placing the battery pack into the CHTX battery pocket, orient the battery pack so
that the sticker is facing down (see Fig. 5).
After installing the battery pack, install the battery cover over the battery and secure by
tightening the thumbscrew at the end of the battery cover (see Fig. 6).
NOTE:
For the battery level indicator on the CHTX units equipped with the standard
status LED or the optional graphic user interface, the battery type dip switch settings
need to be set for the battery pack being used in order to display the correct low battery
level indication.
See Section 3.2.3 on page 16
for details on setting the battery type dip
switches.
3.2.3
Setting Battery Type Dip Switches
For proper indication of the battery level on the CHTX transmitters, the battery type dip
switch settings must be set for the battery pack being used in the transmitter.
NOTE:
The dip switch settings are set at the factory for the battery type ordered with
the system. These settings will need to be changed only if the battery type changes.
The dip switch block is accessed by opening the CHTX housing and flipping the CPU
board over (see Fig. 8). To do this, remove the three clamps found on the front and the
sides of the housing. Unplug the ribbon cable from the CPU board. Remove the CPU
board from the support structure on the housing by removing the four Phillips head
screws in the corners of the CPU board. Set the screws aside for reassembly.
