INSTALLING ALKALINE BATTERIES

WARNING!

◆

DO NOT INSTALL THE BATTERIES IN A HAZARDOUS
ENVIRONMENT WHERE SPARKS COULD CAUSE AN
EXPLOSION.

◆

NEVER DISCARD OLD BATTERIES IN FIRE BECAUSE
EXTREMELY HIGH TEMPERATURES CAN CAUSE BATTERIES
TO EXPLODE.

Note:

◆

It is recommended to use high quality alkaline batteries rather than
manganese batteries to enjoy longer periods of battery life. Do not
use commercially available NiCd batteries.

◆

If you will not use the transceiver for a long period, remove the
batteries from the battery case.

◆

Do not use different quality of batteries together.

◆

When the battery voltage is low, replace all four old batteries with
new ones.

Compared to simplex communication, you can usually
transmit over much greater distances by using a

3

repeater. Repeaters are typically located on a mountain
top or other elevated location. Often they operate at

4

higher ERP (Effective Radiated Power) than a typical
station. This combination of elevation and high ERP

allows communications over considerable distances.

REPEATER ACCESS

Most amateur radio voice repeaters use a separate
receive and transmit frequency. You can set a separate
transmit frequency by selecting the offset frequency and
offset direction with respect to the receive frequency. In
addition, some repeaters may require the transceiver to
transmit a tone before the repeater can be used. To
transmit this required tone, activate the Tone function
and select a tone frequency.

The required offset direction, offset frequency, and tone
frequency depend on the repeater you are accessing.
Consult your local repeater reference.

MEMORY CHANNELS

In memory channels, you can store frequencies and
related data that you often use. Then you need not
reprogram those data every time. You can quickly recall
wanted channels by simple operation. A total of 200
memory channels are available for VHF and UHF.

You can also store a name for each memory channel.
For more information, see “NAMING MEMORY
CHANNELS” {page 20}.

SIMPLEX&REPEATER OR ODD-SPLIT MEMORY
CHANNEL?

You can use each memory channel as a simplex&
repeater channel or odd-split channel. Store only one
frequency to use as a simplex&repeater channel or two
separate frequencies to use as an odd-split channel.
Select either application depending on the operations
you have in mind.

Simplex&repeater channel allows:

• Simplex frequency operation

• Repeater operation with a standard offset

(If an offset direction and offset frequency are stored)

Odd-split channel allows:

• Repeater operation with a non-standard offset

Note:

Not only can you store data in memory channels, but you can also

overwrite existing data with new data.

The data listed below can be stored in each memory
channel:

SCAN RESUME METHODS

■ Selecting Scan Resume Method

Before using Scans other than Priority Scan, it’s
necessary to decide under what condition you want your
transceiver to continue scanning after detecting and
stopping for a signal. You can choose one of the
following modes. The default is Time-Operated mode.

• Time-Operated mode

Your transceiver stops scanning when detecting a signal,
remains there for approximately 5 seconds, and then
continues to scan even if the signal is still present.

• Carrier-Operated mode

Your transceiver stops scanning when detecting a signal
and remains on the same frequency until the signal drops
out. There is a 2 second delay between signal drop-out and
scan resumption to allow time for any responding stations to
begin transmitting.

• Seek mode

Your transceiver stops scanning when detecting a signal
and remains on the same frequency; the transceiver stays
on this frequency even after the signal drops out and does
not automatically resume scanning.

transceiver, or after storing the pack removed from the
transceiver for more than 2 months. It takes several
charge/ discharge cycles before achieving the full battery
pack capacity.

CAUTION:

◆

EXCEEDING THE SPECIFIED CHARGE PERIOD SHORTENS THE
USEFUL LIFE OF THE NiCd BATTERY PACK.

◆

THE PROVIDED CHARGER IS DESIGNED TO CHARGE ONLY
THE PROVIDED PB-38 OR PB-39 NiCd BATTERY PACK.
CHARGING OTHER MODELS OF BATTERY PACKS WILL
DAMAGE THE CHARGER AND BATTERY PACKS.

Note:

◆

Charging should be done within an ambient temperature between
5°C and 40°C (41°F and 104°F). Charging outside this range may
not fully charge the battery.

◆

Always switch OFF the transceiver equipped with the NiCd battery
pack before charging the transceiver. Using the transceiver while
charging its battery pack will interfere with correct charging.

◆

Repeatedly recharging a fully charged battery pack, or almost fully
charged pack, shortens its operating time. To resolve this problem,
use the pack until it is completely discharged. Then recharge the
pack to full capacity.

◆

If the operating time of a battery pack decreases although the battery
pack is fully and correctly charged, the battery pack life is over.
Replace the battery pack.

1 Install the NiCd battery pack onto the transceiver

{page 2}.

• Confirm that the transceiver power is OFF.

2 Insert the DC plug from the charger into the DC IN

jack on the transceiver.

DC IN jack

3 Insert the charger AC plug into an AC wall outlet.

• Charging starts and will take approximately 16 hours for
PB-38 or 15 hours for PB-39.

4 After 16 hours (PB-38) or 15 hours (PB-39), remove

the charger DC plug from the transceiver DC IN jack.

5 Remove the charger AC plug from the AC wall outlet.

TROUBLESHOOTING

The problems described in this table are commonly encountered operational malfunctions. These types of difficulties

1

are usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete
programming. These problems are usually not caused by circuit failure. Please review this table, and the appropriate

2

section(s) of this instruction manual, before assuming your transceiver is defective.

Problem

Nothing appears on
the display when the
transceiver is
switched ON, or the
display is blinking
ON and OFF.

Most keys and the
Tuning control do
not function.

Memory channels
cannot be recalled.

You cannot select
the exact desired
frequency using the

Tuning control.

1 Low supply voltage

2 If using the optional DC cable:

a) Bad power cable or connections

b) Open (blown) power supply fuse

1 Transceiver Lock is ON (Key icon is

visible).

2 The transceiver is in Channel Display

mode.

3 Tone Alert is ON (Bell icon is visible).

There is no data stored in any of the
memory channels.

The current frequency step size needs to
be changed.

Probable Cause Corrective Action

1 Recharge the battery pack or

replace the batteries.

2

a) Check the power cable and

connections, then correct/replace
as necessary.

b) Investigate the cause for the

open fuse. Replace the fuse.

1 Press [F] (1 s) to switch OFF

Transceiver Lock.

2 Press [BAND]+ POWER ON to exit

Channel Display mode.

Problem

You cannot transmit
even though you
press the PTT
switch.

The transceiver
switches OFF for no
apparent reason.

Probable Cause Corrective Action

1 You selected a frequency outside the

allowable transmit frequency range.

2 You selected a transmit offset that

places the transmit frequency outside
the allowable transmit frequency
range.

3 The TX Inhibit function is ON.
4 The Tone Alert function is ON.

The Automatic Power Off (APO) function
is ON.

1 Select a frequency within the

allowable transmit frequency range.

2 Press [F], [REV] repeatedly so

neither “+” nor “–” is visible.

3 Switch OFF the TX Inhibit function.
4 Switch OFF the Tone Alert function.

Switch OFF the APO function.

Packet operation
results in no
connects with other
stations.

1 Physical connections between the

transceiver, computer, and TNC are
incorrect, or software settings in the
TNC are wrong.

2 Different transmit and receive

frequencies are being used. Usually,
you must use the same transmit and
receive frequency for packet.

3 The modulation level from the TNC is

incorrect.

4 There is multi-path distortion.

5 The squelch is open.

1 Recheck all connections using this

manual, your TNC manual and your
computer hardware manual as
reference.

2 If using VFO mode, switch OFF the

transmit offset. If using Memory
Recall, select a simplex memory
channel.

3 Adjust the TNC modulation level

according to the TNC manual.
4 Reorient the antenna. The
strongest

signal does not always provide the

best operation on packet.
