NOTE: Depending on the length of threading available on the anchor bolt, you may need to use the additional
washers provided to elevate the amplifier mounting bracket so that the anchor bolt does not interfere with the
amplifier. If there is not enough threading available to install as shown above, either do not use the additional
washers, or remove the existing nut and washer and mount directly above the tower base plate.
Because this kit is being added to existing towers, installers may find conduit, electrical boxes and other objects
obstructing the area above the anchor bolts where the amplifier brackets mount. These brackets can be installed
on any 2 of the 4 anchor bolts—if you find that it is not possible to fit the brackets in the towers due to specifics of
your existing installation, please call Talk-A-Phone technical support for help.

5) Repeat steps 3 and 4 to install the second amplifier with mounting bracket to a second anchor bolt of
the ETP-MT Tower.
NOTE: Although the amplifier mounting brackets have rain shields, it is the installer's obligation to ensure that
proper drip loops are created with the help of the extension wire, in order to prevent condensation from damaging
the amplifiers.
6) Connect the power supply for the paging amplifier, blue light/strobe and any optional devices (e.g.
VOIP-CM-1.)
7) Use the PAGE VOL screwdriver-adjustable control on the paging amplifier to adjust the volume of the
page output. Rotate the control clockwise to increase the volume and counterclockwise to decrease
the volume.
8) Reattach the rear access panel.
