The SBT-12 must not be used with recharge-
able cells. The SBT-12 does not contain the
thermal and over-current protection circuits re-
quired when utilizing Ni-Cd and Ni-MH cells.
Note: Replace all six cells at the same time in
case of low battery.
To install the SBT-12, turn the open side of the
SBT-12 down, then insert it into the battery com-
partment.
Note: Be sure that the rubber gasket on the SBT-
12 is not loose when inserting.
