SHUTTING DOWN THE TRANSMITTER

TM 11-5820-918-13

(8) Turn off BAT switch.

(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

reconnects batteries to battery charger circuit (even with front panel

BAT 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 2 above.

3-16. For long term storage (more than six months) of transmitters with the non-

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

teries. For transmitters with the rechargeable battery supply, first, perform the

procedure of paragraph 3-15, b above, then remove the complete battery drawer

assembly from the 1024 and store separately to avoid damage from any possible battery

cell leakage.

NOTE

Early versions of the rechargeable battery supply - part number 6025-

1018, Revision A - did not include a battery cutout pushbutton switch

(S1). Later versions - Revision B and on - include the cutout switch

(S1) and a deep-discharge battery protection circuit that prevents bat-

tery damage if the battery supply is accidentally left on and allowed to

discharge. The Revision A version of the battery supply may suffer

permanent damage, and can not be recharged, if it is allowed to com-

pletely discharge or if it is stored for long periods without first being

fully charged. Operating procedures for the Revision A version of the

rechargeable battery supply are the same as for the non-rechargeable

battery supply. However, the Revision A rechargeable battery supply

should be stored only after it is fully charged. If difficulties or poor

performance are encountered with the Revision A battery supply, con-

tact BR Communications for assistance or repair.
