4.6 Power ON procedure
 Power switch to “ON”
 The 3-digit LED display of each section will show “tst“ while all lines
are tested in sequence and batteries checked for the charge level.
 If all tests are passed, the 3-digit LED display will show the UNIT
NUMBER: the Unit is READY TO OPERATE
 Should otherwise any test fail, the 3-digit LED display will issue one of
the warning messages (see the previous paragraph 4.4). In this case:
TURN OFF the instrument, wait some seconds and TURN ON IT
AGAIN: if now the 3-digit LED displays the UNIT NUMBER, probably
it was just a bad reading and all is OK. If otherwise the WARNING
MESSAGE should still appear, DISCARD THE UNIT (it must be
serviced or the batteries re-charged). DO NOT ATTEMPT TO
SWITCH ON THE UNIT AGAIN IF THE FIRST TEST ISSUED A
”FrL” WARNING MESSAGE! THE FAILURE OF THE
INTERNAL SAFETY RELAY COULD BE POTENTIALLY
DESTRUCTIVE!
 If a warning message concerning the internal batteries is received,
probably the SYSTEM BATTERY or the FIRE BATTERIES voltage is
BELOW the minimum value required for a safe operation: the Unit
automatically enters a TOTAL BLOCKING condition.
 A warning message concerning the batteries not always means a
permanent failure of the internal batteries: more frequently the batteries
just require A RE-CHARGE CYCLE. Only if, after AT LEAST TWO
CHARGING CYCLES, the warning message is still issued, then a
permanent failure should be suspected and it is suggested to have the
Unit serviced.
 Any low-battery problem (insufficient charge or failure) can be
recovered in two modes: if the batteries are just low in charge and the
time left before the show is enough, RECHARGE BATTERIES. If
otherwise the batteries have a permanent failure or the problem arrived
when there is not enough time for a full charging cycle, turn the main
switch OFF, and connect an EXTERNAL EMERGENCY BATTERY
PACK. This will allow to perform anyway your show.
 During the whole OPERATING PERIOD, the RX48 Units generate an
INTERMITTENT TONE: this helps to find the Units in the dark when
the show is over and avoid the risk to store the Unit still operating (this
will cause the complete battery discharge in few days with the risk of
permanent damage)
