Weems and Plath Endurance II 135 Barometer/Thermometer - Manual (Page 5)

III. Care of Instrument Case
The Endurance finish is an ultra hard protective coating that is maintenance
free. It is guaranteed not to tarnish or scratch. Wipe the case with a soft,
absorbent cloth periodically to remove dust and marks. Do not use polishing
compounds. Use Weems & Plath Sure Shine to remove stubborn marks.
IV. Quartz Clock Instructions
1) Turn the fastener of the hinged bezel counter-clockwise to release and open.
2) Insert AA alkaline or lithium battery in back of the clock movement.
Follow the diagram on battery housing to make certain the battery is not put
in backwards. Lithium batteries have longer life and are less prone to leak and
perform better than other batteries in hot and cold environments.*
3) To set the time, advance hour and minute hands by turning the knob on
the back of the movement counter-clockwise. To reverse, turn clockwise.
If the clock is left unattended for long periods of time, the battery should be
removed. Otherwise, it could stop working, become corroded and leak acid
which causes damage to the movement and voids
the warranty.*
* Movement damage caused by battery leakage will void the
warranty.
