Care and Servicing
Cleaning the Gauge
After each dive while the Gauge is still assembled, wash the
unit in fresh water and allow to dry
A mild detergent may be necessary to remove grease from
the O-ring grooves
Do not use solvents to clean the Gauge
Do not use any abrasive cleaner, especially on the display
window
O-Ring Seals
When assembling the gauge before a dive fit a new set of O-
rings (see page 19) and ensure they are lubricated with
Molykote
To avoid the risk of a leak: prevent accidental re-use of old
O-rings by destroying them after removal
Batteries
Always remove the battery pack if the Gauge will not be used
for more than a few days
Recharge the batteries periodically even if the Gauge will be
left unused for more than a few days
Only recharge the battery packs with the supplied charger
Occasionally give the batteries a recharge cycle of 14-16
hours to recondition the batteries and extend their life
Environmental
Do not subject the Gauge to tempera
tures greater than 60˚C
(140˚F)
Do not store the Gauge and its kit for long periods in
conditions of high humidity
