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 cut-

out switch (S1) and a deep-discharge battery protection circuit that

prevents battery 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 cannot be recharged, if it

is allowed to completely 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, contact BR Communications for

assistance or repair.
