The following table is a list of possible alarm messages:
Alarm Problem
High Temperature The internal temperature is over 70 °C.
Battery Too Hot Charging has stopped because the battery is too hot, it must
cool down below 60 °C before it can charge.
Battery Too Cold Charging has stopped because the battery is too cold, it must
warm up above 0°C before it can charge.
Battery Low The battery voltage is too low for transmitting (<2.85V). The
battery must be charged before transmitting will be enabled.
Battery Dead The battery is critically low (<2.6V) and must be charged.
The unit will shutdown after 10 seconds if no charger is
connected.
High Noise Background noise has been measured over the set threshold
(see setting “Backg. Noise High”).
Low Antenna Current Antenna current has been measured lower than the set
threshold (see setting “Antenna Current Low”)
No Antenna The unit is trying to transmit but no antenna is detected.
RF Overload This alarm can be caused by (in order of probability):
An RF Power setting that is too high and is causing an
overload.
A battery that is below freezing temperature.
A faulty or deeply discharged battery.
The RF Power setting should be reduced to avoid this alarm.
The Reader will still attempt to read tags but with reduced
performance. It may be necessary to stop READ mode and
then start READ mode again to clear this fault condition.
Low External Power An external charger is connected, and its voltage has
dropped below the set threshold (see setting “External Power
Alarm”).
Tag File Full The current tag file contains more than 20,000 tags. Tags will
continue to be recorded in this file, however only 20,000 tags
can be displayed on the Reader screen.
Low Memory The total free memory has dropped below the set threshold
(see setting “Memory Low”). Tags will continue to be
recorded.
Memory Full There is no free memory remaining, delete a tag file to free
some memory. Tags will not be recorded to permanent
memory, however up to an additional 20,000 tags can be held
in RAM until memory is made available by deleting files. Tags
stored in RAM will be lost if the unit is powered off.
