NOTE: When programming, use either fresh Alkaline

batteries (or an external power supply), to power

the Quick Talk. When programming is finished,

you may either insert Ni-Cd batteries or leave

Alkaline batteries in place.

WARNING: DO NOT attempt to charge Alkaline

batteries from an external +12 VDC

power supply.

When powering Quick Talk with ALKALINE BATTERIES,

set J103 as follows to disconnect the charging current

paths:

a. To set the Quick Talk for use with alkaline batteries,

move Jumper J103 to cover only one pin of the jumper

base, as shown in FIG-4; this setting prevents the

flow of charging current.

b. Dial "943" to program the Quick Talk for use with

alkaline batteries.

When powering Quick Talk with NI-CD BATTERIES,

set J103 as follows to connect the charging current

paths:

c. Cover both pins with Jumper J103, as shown in FIG-

4, to charge the Ni-Cd batteries from the External

Power connection.

d. Dial "944" to adjust the Quick Talk voltage; the unit

then transmits a "Low Battery" phrase.

NOTE: Because Ni-Cd batteries self-discharge rapidly,

you must constantly charge them with an

external +12 VDC power.
