• Assure that the LOCK switch is in the OFF position
• Assure that the radio is powered by either batteries or an
AC adaptor
• Assure that the AC adaptor is plugged into the household
outlet (mains socket) and into the radio’s DC socket. Take
care not to plug it into the ear phone socket or the anten-
na socket. The AC adaptor may be defective
• Assure that batteries are inserted with correct polarity
• Assure that the batteries are not depleted

USING THE LOCK SWITCH
Placing the LOCK switch into the ON position will render all
buttons and the FINE TUNING control inoperative. If the radio
is turned on while LOCK is on, the volume control is still
operative. This is an excellent feature to use when traveling.
Before placing the radio into a suitcase, purse or briefcase,
turn it off and then lock it. This will prevent accidental turn-
on and battery drainage.
PREVENTING BATTERY ACID LEAKAGE
To avoid battery acid leakage, only use high quality alkaline
or rechargeable nickel-metal-hydride batteries. Never intermix
old with new, or different brands or types of batteries. If the
batteries leak, immediately contact the manufacturer of the
batteries and don’t throw them away. Battery acid leakage
is not covered by warranty and voids the warranty.
