◆The charger plug for an AC wall outlet should be used to

disconnect an AC adapter from an AC outlet, and the charger plug

must remain readily operable.

PREPARATION

◆After the battery pack is charged, do not unplug and plug the

charger into the AC outlet again. Unpluging the charger will reset

the charging timer and the battery pack will be charged again.

This could result in over-charging.

◆When the battery is installed on the transceiver and you are

using an optional rapid battery charger, do not charge the battery

from the DC-IN jack. Charging the battery from the DC-IN jack

may result in overcharging the battery which can result in the

shortening of the battery life cycle.

◆If the battery pack is not used for a long time, the battery pack

capacity temporarily decreases. In this case, charge the battery

and use the battery pack until the transceiver stops receiving.

Repeat this procedure several times. The battery pack should

recover its capacity.

◆If the charger is plugged into the DC-IN jack before the battery

pack is attached, turn the transceiver power ON and then OFF

again to initiate charging.

◆Exceeding the speciﬁ ed charge period shortens the useful life of

the KNB-75L battery pack.

◆The provided charger is designed to charge only the KNB-75L

battery pack. Charging other models of battery packs may

damage the charger and battery pack.

◆Do not transmit while charging.

◆When not in use, store the battery pack in a cool and dry place.

◆Before charging the battery pack, ensure that the release lever is

ﬁ rmly closed.

◆Attention should be drawn to the environmental aspects of battery

disposal.

◆It takes approximately 3 hours to charge the KNB-75L with the

optional KSC-25LS.

Charger Error

• While charging, if a problem is detected in the battery,

“Charge Error !!” appears on the display.

• The following conditions create charging errors:

• A short in the battery is detected.

• Overvoltage in the battery is detected.

• When a charge error occurs, no key other than [] will

function.

BATTERY LIFE

Before you operate the transceiver outside using a battery

pack, it is important to know how long the battery pack

will last. The operating times listed in the table below are

measured under the following cyclic conditions:

TX: 6 seconds, RX: 6 seconds, Stand-by: 48 seconds

We recommend you carry extra battery packs with you, in

case the battery pack becomes depleted.

INSTALLING THE BELT CLIP

If desired, you can install the supplied belt clip to the

transceiver.

Attach the belt clip ﬁ rmly using the two supplied M3 x 6 mm

binding screws.

Note：

◆Be careful not to pinch your ﬁ ngers into the belt clip.

CAUTION

• Do not use glue which is designed to prevent screw

loosening when installing the belt clip, as it may cause

damage to the transceiver. Acrylic ester, which is

contained in these glues, may crack the transceiver’s

back panel.

INSTALLING THE HAND STRAP

If desired, you can install the commercially available strap

with sufﬁ cient strength using the holes of the transceiver.

APRS®

APRS DATA COMMUNICATION

• This function uses the APRS format for data

communications including your station position, messages,

etc.

• When data is received from another station directly, via

digipeaters and/or IGate stations, the direction of the

received station (from your station’s perspective), their

distance, and their grid square locator is displayed. Any

comments sent by the other stations are also displayed.

• APRS (Automatic Packet Reporting System) is a

worldwide system introduced by Bob Bruninga, WB4APR.

< APRS® is a software program and registered trademark

of Bob Bruninga, WB4APR.>

Ofﬁ cial APRS Website: http://www.aprs.org

APRS Network

Digipeater

• Digipeater (Digital Repeater) relays digital packet data.

When a Digipeater receives a packet, it saves it to

memory. When the reception ends, the packet data is re-

transmitted on the same frequency. Using Digipeaters, it is

possible to exchange APRS packets long distances.

IGate

• IGate (Internet Gateway) is a very useful and important

feature for APRS as well as Digipeater. IGate stations

bridge APRS packets between RF and the Internet.

By going through the IGate stations, you can enjoy the

communication with the further distant stations which are

not covered only by Digipeaters.

Digipeater stations and IGate stations are operated by the

volunteer people in each region.

BASIC SETTINGS

This part covers only the minimum necessary settings for

basic operation as an APRS handheld portable station. Refer

to the User Manual (detailed instruction manual) on the

Website for more advanced settings.

My Callsign

Program your Callsign using a maximum of 9 alphanumeric

characters including SSID (Secondary Station IDentiﬁ ers)

such as -7, -9, or -14. Unless you program a Callsign, you

cannot transmit APRS packets.

D-STAR

D-STAR INTRODUCTION

• In the original D-STAR (Digital Smart Technologies for

Amateur Radio) plan, JARL envisioned a system of

repeaters grouped together into Zones.

• The D-STAR repeater enables you to call a D-STAR

station in another area through the internet.

• The transceiver can be operated in the digital voice mode,

including low-speed data operation, for both transmit and

receive.

Note:

◆Before starting D-STAR, the following steps are needed.

STEP 1: Enter your Callsign in the transceiver.

STEP 2: Register your Callsign to a gateway repeater.

DV Mode/DR (D-STAR Repeater) Mode
