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 energy below the Occupa­tional Safety and Health Act and Federal Co mmunication
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 within 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 equip-

ment not expressly approved by EFJ ohns on could void the user’s
authority to operate this equipment (FCC rules, 47C FR Part

15.19).

SAFETY INFORMATION

FCC EXPOSURE LIMITS

This mobile radio transceiver was tested by the manufacturer
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 Figure 1 (B) titled “Limits For
General Population/Uncontrolled Exposure” which is from FCC
report OET bulletin #65.

SAFETY INFORMATION

Figure 2 lists the antenna whips and bases recommended for
use in each frequency range. Each model of this radio was tested
with the appropriate antenn a liste d . The ante nna was mount ed in the
center of the roof of a domestic manufactured 4-door passenger
sedan. The radio manufacturer has determined that the user and
service personnel should remain one (1) meter in distance away
from the antenna when transmitting. By maintaining this distance,
these individuals are not exposed to radio frequency energy or
magnetic fields in excess of the guidelines set forth in Figure 1.

NOTE: If the installer or user changes the type or location of the
antenna, they should be aware of the MPE guidelines shown in
Figure 1 and take measures to comply with those guidelines.

GENERAL OPERATION

- Indicates that an option controlled by the AUX switch or

- Indicates that a call has been received on a group programmed
for a call indicator (see page 21). To turn this indication off, press
any key.

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

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 operational.

Determining Volume Level

The relative volum e setting can be determined by noting the
position 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 enabl ed, a short tone soun ds when an option

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

• If a conventional syst em is selected, take the mi crophone off-hook

and if someone is using the channel, voice is heard. If no one is
using the channel, the squelch control can be adjusted counter-

clockwise as described in “Setting Squelch Control” on page 18
and noise is heard. It is not possible to unsquelch the transceiver
in this manner when an LTR-Net or LTR system is selected.

15

GENERAL OPERATION

Backlight Operation

The display and keypad backlight can be controlled by the
BACKLG T menu parameter (see page 33). 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 Modes

The selected system and group are displayed using either a
Numeric or Alpha display mode. The display mode is selectable if
the S/G DISPL menu parameter is available (see page 33). Other­wise, it is fixed in one of these modes by programming.

Numeric Mode

- In this mode the selected system and group
numbers are displayed on t he top l ine as Sxx and Gxx, an d th e group
alpha tag is displayed on the bottom line. For example, System 1,
Group 1 (CAR 220) is displayed as follows. The system alpha tag is
not displayed in this mode.
