1. Introduction
IM401 has a compact size with a various features in the range of 403~470MHz.
Has a various features shown as below.
IM401 constructed with a microprocessor controlled, temperature compensated Phase Locked
Loop(PLL) frequency synthesizer.
The radio features a double conversion receiver and a direct FM
transmitter modulator. A special integrated circuit provides support to sub-audible signaling(CTCSS & DCS)
and most of the receiving parts are switched off periodically in the power save mode to reduce battery current
drain during standby.

5. Antenna Installation
5-1 Antenna Installation and Compliance with Radio Frequency(RF) Energy Safety
Standards
[IMPORTANT NOTE]
To assure optimum performance and compliance with RF Energy Safety standards, this
antenna installation guidelines and Instructions are limited to metal-body vehicles with
appropriate ground planes and take into account the potential exposure of backseat
passengers and bystanders outside the vehicle.
[NOTE]
For mobile radios with rated power of 7 watts or less, the only installation restrictions are
to use only E-tech approved antennas and install the antenna externally on metal body
vehicles.
For mobile radios with rated power greater than 7 watts, always adhere to all
the guidelines and restrictions in 5.2 below.
5-2 Selecting an Antenna Site/Location on a Metal Body Vehicle
1. External installation – Check the requirements of the antenna supplier and install the vehicle
antenna external to a metal body vehicle in accordance with those requirements.
2. Roof top – For optimum performance and compliance with RF Energy Safety standards, mount
the antenna in the center area of the roof.
3. Trunk lid – On some vehicles with clearly defined, flat trunk lids, the antenna of some radio
models (see restrictions below) can also be mounted on the center area of the trunk lid.
For
vehicles without clearly defined, flat trunk lids (such as hatchback autos, sport utility vehicles, and
pick-up trucks), mount the antenna in the center area of the roof.
Before installing an antenna on the trunk lid.
• Be sure that the distance from the antenna location on the trunk lid will be at least 60cm (24
inches) from the front surface of the rear seat-back to assure compliance with RF Energy Safety
standards.
• Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid and
the vehicle chassis.
If these conditions can not be satisfied, then mount the antenna on the roof top !
4. Mounting restrictions for certain radio models
FILE: IM401 service manual.doc
2006.01.10
8 E-TECH Co., Ltd
24/24
For more than 40 Watt VHF models, the 1/4 wave antenna should be mounted only in the
center area of the roof, not on the trunk lid, to assure compliance with RF Energy Safety
standards.
5. Ensure that the antenna cable can be easily routed to the radio.
Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
6. Check the antenna location for any electrical interference.
7. Make sure any other mobile radio antenna on this vehicle is at least 30.48 cm (1 foot) away from
this antenna.
[NOTE]
Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk
and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause severe
receiver interference.
5-3 Antenna Installation Procedure
1. Mount the antenna according to the instructions provided with the antenna kit.
cable to the radio mounting location.
Run the coaxial
If necessary, cut off the excess cable and install the cable
connector.
2. Connect the antenna cable connector to the radio antenna connector on the rear of the radio.
5-4 Completing the Installation
1. Mount the microphone clip to a convenient spot near your radio.
2. Your microphone has a telephone-type connector at the end of is cord.
Plug the microphone
into the control head connector.
3. To complete your radio installation, plug the power cable into the radio power connector.
