INSERTING
THE
BATTERY
1
2
Remove the brown colored tab from the flat, (+)
positive side of the size 312 battery.
Wait one
minute for battery to reach full power before using
(or testing) battery.
Open battery holder gently, using your fingernail or
thumbnail. Pull out on the small lip of the battery
holder located on the lower part of the Ranger-8720.
3
Locate the + symbol on the inside top rim of the
battery holder. This indicates that the flat, positive
side of the battery should face up in the same
direction as the + symbol.
4
Place the battery in the battery holder –
NOT directly inside the Ranger
. Fit the battery in
the holder with the flat, positive (+) side facing up.
5
Close the battery holder.
NEVER force the battery holder closed.
If the holder does not close easily then the battery is probably
upside down.

TIPS
– Never store batteries in the refrigerator. Store them in a dry place at room temperature.
– Keep your batteries in the packaging until you’re ready to use one. Loose batteries can
short out if they come in contact to anything metallic, like another battery or your keys.
– When removing the tab from a new battery, simply stick the tab on your calendar for an easy
way to keep track of how long your batteries are lasting!
Try using the battery magnet located on the end of
the enclosed cleaning tool.
LOW
BATTERY
INDICATOR
–
When the battery is no longer strong
enough to power your Ranger-8720, you will hear a voice prompt say
“low battery” (this repeats every 8 minutes). Your Ranger-8720 will shut
down after you hear a voice prompt say “replace battery”.
