2.1.3 CONNECTING THE POWER SUPPLY

The 200 and 200E indicators ship standard with an external AC adapter.

into a standard wall outlet. Make sure that the AC voltage appearing at the wall

outlet matches the input voltage marked on the AC adapter.

1. Obtain six (6) alkaline “C” cell (UM-2) batteries and install them in the battery

compartment located at the rear of the unit. Be sure to observe the polarity

indicated inside the battery holder.
