SAFETY INFORMATION
DO NOT dispose of the nickel metal-hydride battery pack used by this
radio in fire because it can explode. Dispose of it in accordance with
local regulations. Also, do not short the terminals because it may
become very hot.
NOTE: The above warning list is not intended to include all hazards
that may be encountered when using this radio.
This device complies with Part 15 of the FCC rules. Operation is
subject to the condition that this device does not cause harmful interference. In addition, changes or modifications to this equipment not
expressly approved by the E.F. Johnson Company could void the
user’s authority to operate this equipment (FCC rules, 47CFR Part
15.19).
OTHER IMPORTANT OPERATING INFORMATIO N
Usage in Blasting Areas - To avoid interference with blasting operations,
be sure to turn the transceiver off in areas posted “Blasting Area” or
“Turn Off Two-Way Radio”. Remote controlled RF devices are sometimes used to set off explosives.
Operation in Explosive Atmospheres - Turn the transceiver off when in
an area with a potentially explosive atmosphere. Although rare, the transceiver could generate a spark or a hot surface that could cause an explosion or fire resulting in bodily injury or even death.
Operation in Flammable Atmospheres - Areas with potentially flammable atmospheres are usually, but not always, clearly posted. These
areas may include fueling areas such as gas stations, fuel or chemical
storage and transfer stations, below deck on boats, and areas where the air
contains flammable chemicals or particles such as grain dust or metal
powders. Do not use or transport the transceiver in any atmosphere or
compartment potentially containing flammable gas, liquids, or
explosives.

BASIC OPERATION
BASIC OPERATION
Power-Up Sequence
When power is turned on using the top panel on-off/volume control,
the backlight turns on, all segments and icons in the display are momentarily enabled, and the last seven digits of the transceiver part number are
very briefly displayed. A beep then sounds (if tones are enabled) and the
transceiver is operational.
Backlight Operation
The display and keypad backlight automatically turns on for 3
seconds whenever any key is pressed.
Setting Volume Levels
The relative volume level can be determined by noting the position
of the index on the volume knob. You may also be able to enable a tone
or background noise for use in setting the volume as follows:
• If key press tones are enabled, a short tone sounds whenever any key is
pressed.
• If a conventional system is selected and the monitor option switch is
programmed (see page 50), press this switch and if someone is talking
on the channel, voice is heard. If no one is talking, the squelch can be
adjusted as described on page 49 and noise is heard. It is not possible to
manually unsquelch the transceiver when an LTR-Net or LTR system
is selected.
System/Group Display Mode
Two system/group display modes can be selected. One is a numeric
format and the other is an alpha tag format. To switch between these
modes, press FCN STR. Turning power off does not change the selected
mode. These modes operate as follows:
