OPERATING INSTRUCTIONS

SYMBOLS

By plugging into any 110-120 V., 60 Hz. AC outlet, the desk charger is immediately ready for use. An indicator light shows that the charger is plugged in and ready to charge either one or two No. 71500 or 71670 battery handles.By leaving the handles in the charger, fully-charged instruments are always ready for use. Batteries cannot be over-charged. A completely discharged battery handle can be fully charged overnight.

Attention: Consult ManualCAUTION: NOT FOR USE IN THE PRESENCE OF FLAMMABLE ANESTHETICS.

MAINTENANCE

LEAKAGE CURRENT CHECK

CLEANING

Like any other piece of electrical equipment, periodic electrical inspections should beperformed by qualified personnel. We recommend that this equipment be inspected at least every six months, more often if used under adverse conditions.

The leakage current from exposed metal parts, when a good earth connection is used, should beless than 10 microamps. This equivalent to 9.5 mv in the following circuit.

Do not pour water or any cleaning solutions into the charging wells.Do not autoclave charger, instruments or handles.For repairs, send unit to: WELCH ALLYN, INC. Technical Service 4341 State Street Road Skaneateles Falls, NY 13153-0220
