SHUTTING DOWN THE RECEIVER

TM 11-5820-917-13

b. For receivers with the rechargeable standby battery supply (P/N 6025-1018),

perform these steps:

(1) Operate equipment from normal AC line power for 24 hours (minimum) to

fully charge batteries. (Batteries must not be stored if discharged.)

(2) Turn BATT switch ON at 6025 front panel.

(3) Turn off AC line power to RCS-4B.

(4) Press TEST switch on 6025 front panel and verify green BATT test

indication.

(5) Remove battery supply from 6025 and momentarily press battery cutout

pushbutton (S1) through hole in battery box top cover.

(6) Reinstall battery supply in 6025 with AC line power off.

(7) Press TEST switch on 6025 front panel with AC line power off and BATT

switch ON. Verify that BATT test lamps on front panel do NOT light.

(8) Turn BATT switch OFF.

(9) Secure equipment for shipping or storage.

CAUTION

Do not turn on AC line power to instrument at any time after the batteries

are disconnected with battery box cutout pushbutton until equipment is

ready for normal use. Applying AC line power to unit automatically re-

connects batteries to battery charger circuit (even with front panel BATT

switch off) and slowly discharges batteries when AC line power is removed.

If AC line power is accidentally applied prior to storage, repeat procedure

starting at step b above.

3-25. For long term storage (more than six months) of receivers with the non-

rechargeable standby battery supply, remove and store separately the D-cell

batteries. For receivers with the rechargeable battery supply, first, perform the

procedures of paragraph 3-24 b above, then remove the complete battery drawer

assembly from the 6025, and store separately to avoid damage from any possible

battery cell leakage.
