Voice Terminal Power Supply
Step 1.
Perform this test only if you have an accessory connected to a 34-button
deluxe voice terminal. Make sure the voice terminal power supply is prop-
erly connected to the 103A Modular Jack (it can also be connected to a ter-
minal extension cord) and that power is being supplied from the ac outlet
for the voice terminal power supply. Use a lamp, radio, or similar device
to check the ac outlet (see Figure 38).
