USING BATTERIES
Install six 1.5 volt AA-size (SUM-3 or R6P) or equivalent manganese or alkaline
batteries into the battery compartment.
1. Open the battery compartment cover.
Open the battery compartment cover—located on the bottom panel of
the RY9—by carefully pressing down on the grooved area of the cover
and sliding it outward, in the direction of the arrow as indicated on the
cover itself, and as shown below.
2. Insert the batteries.
Insert the six batteries, being careful to position them according to the
polarity markings as indicated on the bottom panel of the RY9.
3.Replace the cover.
Carefully replace the compartment cover, making sure that it locks
snugly into place.
Always make sure all batteries are inserted in conformity with the +/- polarity markings. Failure to
do so might result in overheating, fire, or battery fluid leakage.
Always replace all batteries at the same time. Do not use new batteries together with old ones.
Also, do not mix battery types, such as alkaline batteries with manganese batteries, or batteries
from different makers, or different types of batteries from the same maker, since this can cause
overheating, fire, or battery fluid leakage.
Do not dispose of batteries in fire.
Do not attempt to recharge batteries that are not intended to be charged.
If the instrument is not to be in use for a long time, remove the batteries from it, in order to
prevent possible fluid leakage from the battery.
Keep batteries away from children.
