Using the 480i CT Cordless Handset
Handset Battery Indicator & Status
The display provides "at a glance" information on the handset battery.
Note: The handset is designed to recharge the batteries automatically, when
required and placed on the charger stand. The battery icon will not flash and
the handset does not charge every time it is placed on the stand. If a defective
battery is replaced, then the battery Icon is not identified until the new battery
is charged for at least 2 minutes.
Volume Control
The volume key, located on the side of the handset, controls both the
receiver and ringer volume.
Note: The volume key can also be used to adjust the right/left cursor to add spaces
or to erase characters on the display when editing or creating names, key
labels etc.
To adjust the receiver volume:
• While on a call, press the top of the key to increase the receiver volume
and press the bottom of the key to decrease the volume. The receiver
volume icon on display will indicate the current volume level. In
absence of a PBX, the receiver volume returns to the default setting after
each call. However, the PBX directive can direct the handset default to
the volume.
To adjust the ringer volume:
• When the handset is not being used for a call, press the top of the key to
increase the ringer volume and press the bottom of the key to decrease
the ringer volume. The handset ringer will sound on each adjustment to
reflect the new setting and the ringer volume icon on display will also
show the current level chosen.
