NOTE: When programming,
use either fresh Alkaline
batteries (or an external power supply), to power
the Quick Assist.
When programming is fin-
ished,
you may either insert Ni-Cd batteries or
leave Alkaline batteries in place.
WARNING: DO NOT attempt to charge Alkaline
batteries from an ex12VDC
power supply.
When powering Quick Assist with ALKALINE BATTERIES
,
set J103 as follows to disconnect the charging current
paths:
a. To set the Quick Assist 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 Assist for use with
alkaline batteries.
When powering Quick Assist 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,
constantly charge them with external +12VDC
power.

TO CONNECT AN EXTERNAL 12 VDC POWER SUPPLY:
The standard Quick Assist is not set-up for use with an
external power supply.
To modify the Quick Assist for use with an external power
supply, use the following instructions.
1. Carefully drill or punch a 0.484" hole in the bottom of
the Quick Assist enclosure.
2. Install Ritron #02500127 strain relief into the drilled
hole.
3. Use Ritron #RPS-203 Power Supply (11-15 VDC,
200 mA), or equivalent, to power the Quick Assist.
The Quick Assist requires 11-15 VDC, 150 mA
minimum.
4. Connect the External Power Supply to Quick Assist
positive and negative terminals, as shown in FIG-6.
