in communication range of a link unit to allow the system to extract the data
and therefore free up memory. While this is happening the % meter in the
lower right corner of the display will be seen to decrement as each
message is sent.
8. CHARGING
There is no on/off switch on the terminal. It is intended that it is either in
use or on charge. No harm will be done to the battery if the terminal is left
on charge for indefinite periods.
To charge the terminal place it in the charging station so that it is sitting with
the display showing and ensure that the terminal is slid all the way down in
the charging station. After a second has elapsed the terminal will beep and
the message “CHG1” or “CHG3” will be displayed. These messages
indicate that the terminal is charging.
The charging cycle and the meaning of the “CHG” messages is as follows.
CHG1 The battery is very discharged and is being slow charged.
When sufficient charge has been put into the battery it will
switch to fast charge.
CHG3 The battery is being fast charged. When the battery is fully
charged it will switch to trickle charge.
CHG4 The battery is fully charged and is now being trickle charged to
maintain its charge.
A fully discharged battery will take around 7 hours to recharge.
9. MAINTAINENCE AND CARE
The NRT302 terminal has been designed to give reliable service in the
intended environment and is largely maintenance free.
9.1 BATTERIES
With normal use the expected life time of the supplied batteries is 500
charge/discharge cycles, after which they should be replaced. For optimum
performance it is recommended that the batteries be replace annually.
