Walter Drake SW8 - Manual (Page 9)

Introduction - Battery Operation and Installation 3
The SW8 receiver is supplied with an AC adaptor to
power the SW8 indoors. The AC ADAPTOR is
designed to be plugged into a wall outlet that supplies
nominal 120VAC, 60 Hz power. Keep curtains and
other flammable materials out of direct contact with
the AC ADAPTOR to avoid overheating.
The SW8 receiver is designed to operate from either
the supplied AC ADAPTOR or from six "D" cell
batteries (not supplied). NOTE: Check the batteries
periodically for leakage. IF UNIT IS TO BE STORED
OR OTHERWISE NOT USED FOR AN EXTENDED
PERIOD OF TIME, REMOVE THE BATTERIES TO
PREVENT CORROSION AND POSSIBLE DAMAGE
TO THE RECEIVER.

- BATTERY COVER REMOVAL AND INSTALLATION
NOTE:
The SW8 does not rely on the batteries for retention
of memory channels. To insure that clocks and timers
are maintained following the loss of AC power or
battery removal, the SW8 must first be connected to a
source of AC power or have batteries installed for a
minimum of 10 minutes. If power is lost after this
minimum 'charge' time, clocks and timer settings are
maintained for a time period of approximately 30
minutes.
