EQUIPMENT CARE
FINISHING OFF
Portable Four Gas Detector is supplied with rechargeable
battery. To charge the battery, ensure that the basestation is
connected to a suitable power
source. Place the instrument in
the basestation. The basestation
employs a locking system to
ensure that the gas detector is
retained under most operating
conditions. To ensure this
operates correctly, ensure that
the gas detector is
orientated such that the
instrument lip will be inserted
under the locking lip and
rear locking catch.
Whilst charging, the instrument will
flash two red LEDs every 10
seconds. When charging is
complete it will light the green LEDs
constantly. A fully discharged
battery will typically require 7 hours
to recharge.
To remove the Gas Detector press
down on the rear locking catch.

Any alarm will cause the backlight to be switched on
automatically.
LLaattcchhiinngg AAllaarrmmss ((ddeeffaauulltt))
In the latched condition, once an alarm occurs, both
audible and visual alarms continue to operate even after
atmospheric hazard has cleared. Pressing any of the
instrument buttons will clear an alarm. Any subsequent
alarm will reactivate the audible and visual alarms.
NNoonn--llaattcchhiinngg AAllaarrmmss
In this mode, should a gas alarm occur, the instrument
would enter an alarm condition. When the reading
returns to normal levels, the audible and visual alarms
will stop.
VViibbrraattiinngg AAllaarrmm
Any alarm condition that activates the audible and visual
alarms will also activate the built-in vibrating alarm.
RReesseettttiinngg aann AAllaarrmm
If an alarm condition occurs, it is possible to cancel the
alarm by pressing any of the buttons, once the gas
measurements have returned to a safe level. Otherwise,
the instrument will remain in the alarm condition, but
the audible alarm will be muted. Any subsequent alarms
that occur 1 second after the previous alarm has been
reset will reactivate the audible alarm.
FFaauulltt && WWaarrnniinngg CCoonnddiittiioonnss
In addition to the gas alarms, the gas detector includes a
number of auxiliary alarms to safeguard proper use of
the instrument. At switch on, the gas detector performs
an electronic self-test that assures the user of proper
performance. When the gas detector detects that an
electric fault or failure condition has occurred, the
audible and visual alarms are activated and an
explanatory message will be displayed.
