STATUS CODE DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION

-15 Battery voltage is too low or control

card is mis-adjusted. This status code will be displayed when the battery

volts are less than 1.95 volts per cell at initial key

switch on. See table below.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Discharged battery
•=Check battery for proper open circuit voltage
as shown in “Trouble Shooting Diagram”,
charge battery, if required.
Defective battery
•=Check each battery cell for proper voltage
(greater than 1.95 volts at cell). Replace or
repair battery.
Incorrect control card adjustment.
•=Check Function 15 for proper adjustment for
battery being used. See Handset instruction
sheet for details. Adjust to proper settings.
