Do not short circuit the battery. Use care in handling batteries in order to not
short the battery with conducting materials such as rings, bracelets, and keys.
The battery or conductor can overheat and cause burns.
Power requirements
Both the M2616CT telephone and the M2018 telephone are loop powered.
Loop power uses +15 V and –15 V sources and assumes 3500 feet maximum
loop length of 24 AWG (0.5 mm) wire and a minimum of 13.5 V at the
telephone terminals. The RF deck that powers the handset requires a wall
transformer (Class 2 power supply Output rated at 7.5v dc).
The M2616CT handset uses rechargeable Nickel-Cadmium batteries. Both a
700 mAh and 1000 mAh battery, with or without a vibrate alerter, are
available.
Battery charge time for the 700 mAh battery takes approximately 2.25 hours
when attached to the handset, and provides approximately four hours
continuous talk time if the handset backlight is turned on. If the handset
backlight is turned off, up to five hours of continuous talk time is provided,
depending on usage. Up to 72 hours of standby battery time is provided when
the handset is off the base unit.
The 1000 mAh battery takes up to 2.5 hours to charge when attached to the
handset and provides approximately 5.5 hours continuous talk time, if the
handset backlight is turned on. If the handset backlight is turned off, up to
seven hours of continuous talk time is provided, depending on usage. Up to
86 hours of standby battery time is provided when the handset is off the base
unit.
The batteries charge in both the handset and the base unit. The spare
battery-charging port on the base unit provides a "trickle charge" that charges
a battery at a slower rate than through the handset.
If the power supply fails, the optional spare battery in the spare battery
charger powers the handset. Available talk-time depends on how much
charge remains in the battery. The base phone continues to function without
the handset in handsfree mode, even if the power supply fails and the spare
battery is discharged or not available.
