52. If the interrogation is unsuccessful there are two possibilities:
a) If there is no contact between system and transceiver, the following display is
shown:
Absent or PROGRAMMED MESSAGE
b) If there is no user number associated with the transceiver address the following
display is shown:
Absent ---- or PROGRAMMED MESSAGE ----
53. If the transceiver is switched off when inserted into the rack with a serviceable battery
unit, the charge lamp will light but no absence registration will take place. If the battery
unit is flat when inserted in the rack, the transceiver will switch on, the charge lamp
illuminates and registers absent as normal.
54. If the transceiver is placed in the absence rack with a totally-discharged battery pack,
one of the following situations will arise:
a) the charge LED will light, the absent or programmed message will be displayed.
b) the charge LED will light, flashing `E's will be displayed.
c) the charge LED will light, the transceiver will switch on and start its initialisation
routine.
RECHARGING THE BATTERY PACK
55. If the battery pack voltage becomes too low during a transmission, the transceiver
sends the un-talk code at low volume and then keys down. A `low-battery' buzz is then
generated if the option is enabled.
56. A discharged battery pack may be trickle-charged by inserting it into the pocket of a
P622 or P623 Trickle Charging Unit. Alternatively, the battery pack may be fast-
charged by inserting it into the pocket of a P616 or P619 Personal Charging Station.
Discharged battery packs may be re-charged with or without the transceiver attached.
57. Brand new battery packs normally require a few charge and discharge cycles before
they settle into their normal charging behaviour. New uncharged battery packs should
be charged three or four times before initial use. This is achieved by taking the charged
battery pack/transceiver out of the charging station and, once the LED charge indicator
is extinguished, inserting it again.
