Getting Started
Read all the information in this section
before you use your handset.
Handset information
Ensure that the adapter voltage is the
same as the electrical outlet voltage.
The 743X/744X handset uses radio
signals and does not guarantee a
connection in all circumstances. Do
not rely on a cordless handset to
make emergency calls.
Never use your handset:
• in the vicinity of electrical
detonators
• in shielded rooms
• in areas where radio transmission is
forbidden
• in aircraft
Do not place a handset near:
• water, moisture or damp areas
• heat sources, direct sunlight or
unventilated areas
• devices which generate strong
magnetic fields such as electrical
appliances, fluorescent lamps,
computers, radios, televisions or
fax machines
• areas where the handset can be
covered, its ventilation impaired,
liquid spilled on the unit or objects
inserted into the handset through
any openings.
7
• areas with dust, vibration, shock or
temperature extremes
Check for small metal objects in the
handset earpiece/mouthpiece before
using the handset.
Do not store or locate flammable liq-
uids, gases, or explosive materials in
the same compartment or vicinity as
the cordless handset, its parts or
accessories.
Battery information
Read the following information before
you handle the batteries:
• Do not replace the batteries in
potentially explosive environments,
such as rooms where flammable
liquids or gases are present.
• The battery will explode if disposed
of in a fire.
• Do not charge the batteries unless
you use the Nortel Networks
approved charger and the proper
batteries.
• Only use battery type NT7B65LD in
the 743X/744X handset. Do not
use these batteries with other
products. These batteries were
designed specifically for use with
the 743X/744X handset and the
743X/744X charger ONLY.
Improper use of the batteries may
result in fire hazard.
• Do not do anything that would
cause the battery to short circuit.
• Do not let the battery or the charger
come into contact with conductive
metal objects.
8
Installing battery
The battery is connected to the hand-
set when it is shipped from the fac-
tory.
1 To change the battery unscrew
the plate on the rear of the
handset to access the battery
compartment. Use a normal
screw driver.
2 Insert the screwdriver into the
small crack behind the blind cover
and break to open the handset.
3 Place the battery plug in the slot
in the battery box.
4 Insert battery with the label
readable.
5 Replace the back cover.
9
Charging battery
When charging the battery for the first
time, it is necessary to leave the
handset in the charger for 14-16
hours for the battery to be fully
charged.
During normal operation, it takes
approximately 3.5 hours to charge the
handset from fully discharged to its
full capacity.
• Place the handset in the charger.
For correct charging, be sure the
room temperature is between 0°C
and 25°C. Do not place the
handset in direct sunlight. The
battery has a built-in heat sensor
which will stop charging if the
battery temperature is too high.
If the handset is turned off when
placed in charger, only the LED
indicates the charging. When
handset is turned off, the LED
10
flashes at a low frequency while
charging and lights constantly
when the charging is finished.
There will be no reaction on
incoming calls.
If the handset is turned on when
charging, the display shows the
charging status. The display goes
back to normal mode when fully
charged. It will not vibrate.
Auto-answer is inactive. The
handset reacts normally for
incoming calls.
It is necessary to recharge the battery
when the display shows BATTERY
LOW, or if the handset cannot be
turned on. When the battery is fully
discharged, up to 10 minutes may
pass before charging begins (display
lights up). When the charger begins
the charging, status is shown in the
display if the handset is turned on.
Checking battery capacity
In the BATTERY MENU it is possible
to see the remaining battery capacity.
For reading the correct capacity, the
handset has to be removed from the
charger for at least one hour.
1 Press MENU ( ) and use the <
or > keys to reach the BATTERY
MENU.
2 Press 3 to enter the BATTERY
MENU, and see the current status
of the battery capacity.
3 Press 3 to return to the menu
system, or press MENU ( ) to
quit.
11
The indication on the display is not
necessarily an exact reflection on the
remaining speech time, but only an
indication of the voltage on the bat-
tery.
Battery disposal
Defective batteries must be returned
to a collection point for chemical
waste disposal.
Warning: Nickel metal hydride
batteries must be disposed of
properly. Do not dispose of the
batteries in office or household waste.
Nickel metal hydride batteries are
recyclable. You can help preserve the
environment by returning your
unwanted batteries to your nearest
recycling center for recycling or
proper disposal.
Contact your system administrator for
more information about battery dis-
posal and recycling centers in your
local area.
