2. Use the numeric keypad to enter 6 (which is roughly half of 11) and press ENT.
3. Press either K1, K2, or K3. The display reads:
ORIG OFF HOOK IF M-LD >39 V DEFAULT
K1 K2 K3 K4
In this case the 930i provides an Off Hook indication on the ORIG LEDs if the voltage on the 'M' lead
exceeds the 39 V threshold. This value has to be changed to 20 V (roughly half of 39).
4. Enter 20 from the numeric keypad and press ENT.
5. Press K1, K2, or K3. The display reads:
TERM ON HOOK IF E-LD >39 V DEFAULT
K1 K2 K3 K4
The 930i provides no line signalling indication if the voltage on the 'E' lead is below the high threshold
of 39 V but above the low threshold of 11 V. The high threshold can be changed to 20 V as before.
6. Press K1, K2, or K3. The display reads:
TERM OFF HOOK IF E-LD >11 V DEFAULT
K1 K2 K3 K4
An Off Hook indication on the front panel LEDs will be provided if the voltage on the 'E' lead is below
the 11 V low threshold.
7. Change the voltage to 6 V (roughly half of 11).
8. Press the Option Menu function key to exit when the thresholds have all been set.
9. Return to each of the displays after you are finished testing and reset them to their default values
to avoid problems on normal circuits.
