Controls and Display
Note
The appearance of the 51FIRE ES Model II and III radios are identical to the 51SL ES
Model II/III radios except for the yellow casing for the 51FIRE radios.
Microphone
- The microphone is located behind the small opening shown in Figure 2.1.
For best results, hold the radio 2-3 inches from you mouth and speak at a normal
conversational level. Do not shout since it distorts your voice and does not increase range.
Display
- This is a graphical LCD (Liquid Crystal Display). The display backlight can be
programmed to turn on when any key/button is pressed (or pressed and held, depending
upon programming), or when the Backlight option button is pressed or menu parameter
selected (see Section 3.5).
Up/Down Buttons
- Select zones when multiple zones are programmed (see Section 3.3).
Pressing the up button selects the next higher number and pressing the down button selects
the next lower number. These buttons also provide up/down select in the menu mode and
in other modes when up/down select is required.

connector is pulled low. The logic then automatically disables the internal speaker.
