1.3.8 Install Batteries (Optional)
While it is not necessary for you to install batteries in your 2740 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.
1. Make sure the AC cord remains attached to the telephone and to an electrical outlet
2. Turn the telephone over.
3. Remove the desk stand if attached.
4. Remove the battery door by using the tip of a ball point pen, paper clip, or similar object to release
the battery door tab.
5. Remove the old batteries.
6. 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.
7. Close the battery cover.
Use caution when disposing of old batteries. Do not dispose of them in a fire. They may explode.
