1.3.7. Assign a Station Number
Station 01 must be the first number assigned. Station 01 is required for programming select features
on the 2750. Refer to Section 2.1 for detailed instructions on assigning a station number.
1.3.8. Connect Cords to Telephone
If the wall jack is labeled Lines 1 & 2, connect the short telephone line cord to the jack on the
telephone labeled L1/L2. If the wall jack is labeled Lines 3 & 4, connect the short cord to the jack on
the telephone labeled L3/L4. Connect the long telephone line cord to the other line jack on the
telephone and thread it through its long groove on the bottom of the phone, then plug the AC power
cord into the adapter jack on the bottom of the telephone, threading the power cord through its long
groove on the bottom of the phone. Thread the short telephone cord through the square hole in the
center of the wall mount bracket, and then attach the wall mount bracket to the base of the telephone.
1.3.9. Install Batteries (Optional)
While it is not necessary for you to install batteries in your 2750 telephone for it to function normally,
we do recommend that they be installed. The batteries are not needed to preserve your memory dial
numbers, because all memory dial numbers are stored in static memory. The purpose of having
batteries installed is so that the telephone itself can function for up to two hours in the event of a power
failure. The telephone uses 3 AAA size batteries. We recommend using alkaline batteries.
To install Batteries, do the following.
a. Make sure the AC cord remains attached to the telephone and to an electrical outlet
b. Turn the telephone over.
c. Remove the battery door by using the tip of a ball point pen, paper clip, or similar object to
release the battery door tab.
d. Remove the old batteries.
e. Insert 3 pieces of new size AAA 1.5V alkaline batteries. Please note the “+” and “-” markings in
the battery compartment for the orientation of the batteries.
f. Close the battery cover.
Use caution when disposing of old batteries. Do not dispose of them in a fire. They may explode.
