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 ex12 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
ex12 VDC power.
