Battery
and
Charging
Before first use, fully charge the battery.
When charging, use only the supplied mains plug-top power supply.
Charging will typically take 3 hours
. Please ensure a full charge is given as the battery state
reading can be in error after a short charge.
A fully charged battery will operate the GSM Signal Analyser for up to 12 hours.
The battery state may be read on the
Monitor
screen (see page 16).
When the charger is connected, the unit is always on and the On/Off button will not turn the
unit off. The charger can be left plugged in indefinitely.
When the charger is disconnected, the GSM Signal Analyser will automatically switch off
within one minute or after the preset time has expired.
If the GSM Signal Analyser is left switched on and unused (no buttons are being pressed), the
unit will automatically switch off after a preset time to preserve the battery life. The preset time
may be changed in the
Setup
screen (see page 9).
The internal battery is a Solid Electrolyte Lithium long type that may be transported, charged
and used in any orientation. It should be protected from frost and temperatures above 40°C.
As with all rechargeable batteries, over several years, its capacity to store power will degrade. If
the operational life of the battery reduces below 1 hour, contact your supplier for replacement
information.
Do not
attempt to open the case or remove the battery.
