9. Receiver Battery Circuit Test
a. Performance Check
(1) Disconnect dc power supply from XMIT BAT and connect to RCVR BAT,
observing polarity (large pin positive).
(2) Set and hold BAT TEST switch to RCVR position while adjusting dc power
supply for an indication at center of yellow area on TI meter. If multimeter does not
indicate between 4.9 and 5.1 V dc, perform b below.
(3) Release BAT TEST switch and adjust dc power supply output fully ccw.
b. Adjustments
(1) Adjust dc power supply for an indication of 5 V dc on multimeter.
(2) Set and hold BAT TEST switch to RCVR position while adjusting R14 (fig. 1)
for a meter indication at center of yellow area (R).
10. Internal Battery Circuit Test
a. Performance Check
(1) Disconnect dc power supply from RCVR BAT and connect to INTERNAL
BATTERY, observing polarity.
NOTE
Upper left pin is positive, lower right pin is negative, located in
TI INTERNAL BATTERY compartment.
(2) Set FUNCTION switch to INT BAT.
(3) Adjust dc power supply for a TI meter indication at lower edge of yellow area. If
multimeter does not indicate between 9.8 and 10.2 V dc, perform b below.
NOTE
Leave equipment setup connected for use in paragraph 11
below.
b. Adjustments
(1) Adjust dc power supply to 10 V dc.
(2) Adjust R8 (fig. 1) for a meter indication at lower edge of yellow area (R).
a. Performance Check
(1) Connect calibrator to TEST PROBE TIP and ground and set TI FUNCTION
switch to VFO or VCO.
(2) Set calibrator for an output of 0.0 VDC.
(3) Adjust dc power supply output for a 12-V dc indication on multimeter. If TI
meter does not indicate at center ALIGN mark, perform b below.
