Suspend mode allows you to suspend, but not terminate active applications. In this mode, the display will
turn off and the JETT will cease serial port operations. For battery-powered units, Suspend mode also
conserves battery power. To place the unit in Suspend mode, press and release the On/Off switch. To take
the JETT out of Suspend mode, press and release the On/Off switch again. The display will turn on and the
JETT will resume running any suspended application, but you must restart any serial port operations. If you
attempt to resume immediately after suspending the JETT or vice versa, the unit will delay three seconds
before resuming or suspending.

The JETT•ce comes with a rechargeable Nickel Metal Hydride (NiMH) battery pack that can provide up to
six hours of operating time on a full charge (depending on power management settings and peripheral use).
You will need to charge the Nickel Metal Hydride rechargeable battery pack a minimum of three hours
prior to first use. Please note that the battery pack will not attain maximum capacity until it has been
charged and discharged approximately four times. As a result, you may experience shorter than expected
operating time on the first few uses of the product.
NiMH batteries are an extremely stable and dependable source of electrical energy, but can be
sensitive to extreme temperature. If
you charge the
battery pack in extreme hot or cold, it will not
attain a full charge, and as a result will exhibit decreased useable time until it recharging again.
As a precaution against overheating, the JETT
has
built
-
in temperature sensors that will suspend
the charging process if the battery becomes too warm.
Because t
he battery
pack
is an electrical device
, you sho
uld not expose
it
to moisture or wet
environments. If the battery becomes wet, wipe it dry and then allow it to dry thoroughly for
several hours before attempting to use or charge it.
Do not leave the battery pack in a fully discharged state for extended periods. This condition may cause one
or more of the cells within the battery pack to fail. When this occurs and the battery pack is subsequently re-
charged, the failed cell will reduce the total voltage capacity of the battery pack, thus making the battery
appear to discharge faster.

When using the NiMH battery pack, the CHARGE/LOW BAT LED will indicate the current battery status
as shown in the table below.
Table 3-1: Charge\Low Battery Indicator Functions
Function Description
CHARGE With the power supply connected, the CHARGE/LOW BAT LED will indicate one of
following conditions:
ƒ High Power Charge —the LED will turn solid green until the battery reaches
80% capacity of its charge capacity
ƒ Trickle Charge— the LED will blink green about four times a second when the
battery reaches 80% capacity of its charge capacity
LOW BAT With the power supply disconnected, the CHARGE/LOW BAT LED will indicate one
of following conditions:
ƒ Batteries are low —the LED will blink red once per second when there is
approximately 30 minutes of power remaining
ƒ
Batteries are very low —the LED will turn solid red when there is
approximately 10 minutes of power is remaining
