15. Battery Compartment Cover
16. Battery Cover Thumb grip
To change batteries:
Place your thumb on the battery cover thumb grip
and pull back on the battery compartment cover to
open the battery compartment. Carefully flip the
cover up and slide it to the back of the opening and
push it slightly downward to release the battery
sled into your hand. The sled may contain six 1.5V
AA batteries or it may be an optional BAT850
NiMH rechargeable battery pack. In the case of a
BAT850 battery pack, remove the entire pack and
put it into the AC850 charger. If the sled contains
six 1.5V AA batteries, remove them from the sled
and replace them with six fresh ones.

Carefully slide the battery compartment cover back
over the compartment until its latches securely in place.
Infrared Window
The infrared window provides capability for interfacing
with a PDA for easy PRO850 configuration setups.
Optional HME PDA850 software is required.
Dual-Receiver Operation
A Beltpac equipped with the optional second receiver operates a little differently from a single-receiver Beltpac.
When a user switches from Channel 1 to Channel 2 on a single-receiver Beltpac, the microcontroller inside the
Beltpac automatically switches the receiver frequency from Rx1 to Rx2. That means that it is not normally
possible for the user to hear both intercom channels at the same time. With a dual-receiver Beltpac, there is no
need to change frequencies and the primary receiver always stays tuned to Rx1 and the second receiver stays
tuned to Rx2. The user is then able to hear both intercom channels at the same time and adjust the relative
volume between them.
This difference makes the operational characteristics of a dual-receiver Beltpac slightly different from those of a
single-receiver Beltpac. On a single-receiver Beltpac, only one of the A or B indicator lights will be on
indicating the current channel. On a dual-receiver Beltpac, both A and B indicator lights will be on indicating
that both receivers are active. If one of the buttons is programmed to toggle between channels, the current
channel indicator will blink. An additional feature of the dual-receiver Beltpacs is the ability to talk on both
intercom channels at the same time.
