INSTALLING THE
BACKUP BATTERIES
The System 612 requires AC power to
operate. However, if AC power fails or
you unplug the speakerphone, the three
AAA backup batteries (not supplied)
save stored information. We recom-
mend you use alkaline batteries, such
as RadioShack Cat. No. 23-555.
Cautions:
• Always use fresh batteries of the re-
quired size and type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
• Disconnect the System 612 from the
phone line(s) before replacing the
backup batteries.
Notes:
• To avoid losing stored information
when replacing the batteries, leave
the AC adapter plugged in, and
have fresh batteries ready to install
before removing the old ones.
• Replace the batteries when
BATT
appears.
1. Use a Phillips screwdriver to remove
the screw from the battery compart-
ment cover, then remove the cover.
2. Install three AAA batteries (not sup-
plied) as indicated by the polarity
symbols (+ and –) marked inside the
battery compartment.
3. Replace the cover and the screw.
Cautions:
• Always remove old or weak batter-
ies. Batteries can leak chemicals
that can destroy electronic parts.
• Dispose of old batteries promptly
and properly.
SELECTING A LOCATION
You can place the Speakerphone on a
on a desk top, shelf, or table, mount it di-
rectly on a wall, or mount it on a stan-
dard wall plate. Select a location that is:
• near an AC outlet
• near the desired telephone line
jack(s)
• out of the way of normal activities
• away from electrical machinery,
electrical appliances, metal walls or
filing cabinets, wireless intercoms,
alarms, and room monitors
