BULLETIN # 1015
MODEL: TS-50S
SUBJECT: Lithium Battery Replacement Notes
Procedure:
Immediately after replacing the Lithium battery you must cycle the radio
ON then OFF. Failure to follow this procedure will result in premature
failure of the battery. If the power is not cycled ON then OFF the
microprocessor will immediately begin drawing approximately 1 mA of power
from the Lithium battery, resulting in poor battery life.
When the battery is replaced we recommend the insulation sheet also be
changed. Part numbers for the battery and insulation sheet follow.
Parts Required:
Qty Description Kenwood Part No. Circuit Description
1 Lithium Battery W09-0515-05 BA1
1 Insulating Sheet F20-0521-04 None
Caution: This modification requires soldering equipment rated for CMOS type
circuits. It also requires familiarity with surface mount soldering
techniques. If you do not have the proper equipment or knowledge do not
attempt this modification yourself. Seek qualified assistance.
Time required for this modification is 15 minutes or less.
