Li-ion Battery Safety 
Instructions

 WARNING

Failure to read, and follow Li-ion battery safety 
instructions, and warnings may result in fire, 
personal injury, and property damages if the 
battery is charged and/or used improperly.

•  DO NOT SHORT CIRCUIT. Short circuits 

may cause a fire and injury!

•  Charge battery fully before first use.
•  To charge the battery use only the 

specifically designed USB charger, 
provided in the packaging.

•  Do not keep a bare battery in your 

pocket, purse, or anywhere together 
with other metal (conductive) objects.

•  If the battery is damaged in any 

way stop using the dive computer 
immediately.

•  Do not immerse in any liquid or allow 

the battery to get wet.

•  Do not place the battery in high-

pressure containers, microwave ovens, 
or on induction cookware.

•  Immediately discontinue use if, while 

using, charging or storing, the battery 
emits an unusual smell, feels hot, 
changes color or shape, or appears 
abnormal in any other way.

•  Do not carry, or store the batteries 

together with any conductive metal 
objects.

•  Do not expose the battery to excessive 

sunlight or heat.

•  Do not disassemble, or modify the 

battery.

•  Keep the battery away from children, 

and pets.

•  Never charge, or store the batteries 

inside your car in extreme temperature. 
Extreme temperatures (low or high) 
might ignite the battery, and cause a 
fire.

•  Do not connect positive, and negative 

battery contacts intentionally, or 
unintentionally.

•  Do not reverse the positive (+) and 

negative (-) terminals when charging, or 
using the battery.

•  Never charge the battery at a current 

exceeding manufacturer-specified 
charging current.

•  Never completely discharge the Li-ion 

battery.

•  After the battery is discharged, don’t 

leave it discharged. Charge battery as 
soon as possible 

•  It is your responsibility to determine 

that your charger and host device work 
properly.

•  On battery electrolytes exposure to skin, 

flush with water immediately.

•  If eye exposure occurs, flush with water 

for 15 minutes, and seek emergency 
care immediately.

•  When your Li-ion battery reaches 

the end of its lifetime, it can only be 
replaced by an authorized SCUBAPRO 
service center. Do not open your dive 
computer or try to replace the battery 
yourself!

Operating modes

The G2TEK has 4 operating modes:

• 

Charging and USB communication 
mode. 

When connected to a 

USB device the G2TEK’s battery 
automatically starts charging. At the 
same time, you can access either the 
flash memory or the logbook using the 
LogTRAK program. 

• 

Sleep mode.

 In this mode the display 

is off, but the G2TEK still updates 
desaturation and monitors ambient 
pressure for altitude changes, etc. 
This mode is activated automatically 
at the surface after 3 minutes without 
operation. 

• 

Surface mode. 

After a dive or when 

manually activated, the display is on and 
you can change settings or operate the 
G2TEK with its buttons. The Bluetooth 
interface can be activated in this mode.

• 

Dive mode. 

This mode is activated 

when the computer reaches a depth 
of 0.8m/3ft or more. In this mode 
the G2TEK monitors depth, time,
