18) PROGRAMMING REHABILITATION IN CASE OF BLOCK (Prg no)
In the event program access is blocked the display will show SET and then display “noP”.
To gain access, press the ENT key and return to normal operation. Touch the PRG key
and then, press and hold the TEST key for approximately 7 seconds until the flashing
PRG screen display ends, and the message nCH is displayed.
NOTE: this procedure removes the lockout feature. To block access again, this feature
must be reprogrammed.
19) WARRANTY
The “T” series units are warranted for a period of 12 months from the delivery date
marked on the unit.

Warranty will be voided if the unit is found to be tampered with or when it has been dam-
aged as a result of incorrect input or power supply connections (out of the max working

tory overvoltages. Freight expense is not covered under warranty.
