SAFETY INFORMATION

SAFETY INFORMATION

The FCC has adopted a safety standard for human exposure to RF en­ergy. Proper operation of this radio under normal conditions results in
user exposure to RF ener gy bel ow the Occ upati onal Saf ety and He alth
Act and Federal Communication Commission limits.

WARNING

DO NOT allow the antenna to touch or come in very close proximity
with the eyes, face, or any exposed body parts while the radio is trans­mitting.

DO NOT operate the transmitter of a mobile radio when a person out­side the vehicle is within one (1) meter of the antenna.

DO NOT operate the transmitter of a stationary radio (base station or
marine radio) when a person is wi thin one (1) meter of the antenna.

DO NOT operate the radio in explosive or flammable atmospheres.
The transmitted radio energy could trigger blasting caps or cause an
explosion.

DO NOT operate the radio without the proper antenna installed.

DO NOT allow children to operate or play with this radio.

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

SAFETY INFORMATION

FCC EXPOSURE LIMITS

This mobile radio transceiver was tested by the manu facturer with
an appropriate antenna in order to verify compliance with Maximum Per­missible Exposure (MPE) limits set under Section 2.1091 of the FCC
Rules and Regulations. The guidelines used in the evaluation are derived

from Table 1 (B) titled “Lim its For General Population/Uncontroll ed
Exposure” which is from FCC report OET bulletin #65.

GENERAL OPERATION

- Indicates that a ca ll has been received on a group programmed for a

call indicator (see page 24). To turn this indication off, press any key.

- Indicates that the m oni tor mode is enabled. This mode disables Call
Guard squelch and other squelch control features so that all messages are
heard on conventional systems (see page 44).

- When only is displayed, the selected or displayed group is
scanned as a first priority group. When is displayed, it is scanned as a
second priority group (see page 46).

GENERAL OPERATION

Power-Up Sequence

When power is turned on, the backlight turns on, all segments 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 ready to be used.

Determining Volume Level

The relative volume sett ing ca n be d etermi ned by notin g t he pos ition
of the index on the volume knob. You may also be able to enable a refer­ence tone or background noise for use in setting the volume. Proceed as
follows:

• If key press tones are enabled, a short tone sounds when an option

switch is pressed or the Select switch is pressed or rotated.

• If a conventional sys tem is sel ected, ta ke the micro phone of f-hook a nd

if someone is using the channel, voice is heard. If no one is using the
channel, the squelch control can be adjusted counterclockwise as

described in “Setting Squelch Control” on page 18 and noise is heard.
It is not pos sible to unsquelc h the transceiver in this manner when an
LTR system is selected.

GENERAL OPERATION

Backlight Operation

The display and keypad backlight can be controlled by the BACK­LIGHT menu parameter (see page 38). The three states that can be
selected are Bright, Dim, and Off. If this menu parameter is not select­able, the backlight is fixed in one of these states by programming.

System/Group Display Information

The currently select ed s yst em and group are displayed using either a
Numeric or Alpha Tag display mode. The display mode is selectable if
the S/G DISPL menu parameter is available (see page 32). Otherwise, it
is fixed in one of these modes by progr amming. These modes function as
follows:

Numeric Mode

- In the numeric mode, the selected system and group
numbers are displayed on the top line as Sxx and Gxx, and the group
alpha tag is displayed on the bottom line. For example, System 1, Group
2 (CAR 220) is displayed as follows. The system alpha tag is not
displayed in this mode.
