General Radio Operation

Receive / Transmit

Radio users who switch from analog to digital radios often assume
that the lack of static on a digital channel is an indication that the radio
is not working properly. This is not the case. Digital technology quiets
the transmission by removing the “noise” from the signal and allowing
only the clear voice or data information to be heard.

This section emphasizes the importance of knowing how to monitor a
channel for traffic before keying-up to send a transmission.

Special Radio Features

Trunking System Controls

Failsoft

The failsoft system ensures continuous radio communications during
a trunked system failure. If a trunking system fails completely, the
radio goes into failsoft operation, and automatically switches to its
failsoft channel.

During failsoft operation:

• Your radio transmits and
receives in conventional
operation on a predetermined
frequency.

• You hear a medium-pitched
tone every 10 seconds.

When the trunking system returns to normal operation, your radio
automatically leaves failsoft operation and returns to trunked
operation.

Out-of-Range

If you go out of the range of the system, and can no longer lock onto a
control channel, you hear a low-pitched tone.

Your radio remains in this out-of-range condition until

• It locks onto a control channel,

• It locks onto a failsoft channel, or

• It is turned off.

ASTRO XTS 2500 Model I 35

Special Radio Features

Radio Care

Cleaning

To clean the external surfaces of your radio:

1 Combine one teaspoon of mild dishwashing detergent to one

gallon of water (0.5% solution).

2 Apply the solution sparingly with a stiff, non-metallic, short-

bristled brush, making sure excess detergent does not get
entrapped near the connectors, controls or crevices. Dry the
radio thoroughly with a soft, lint-free cloth.

3 Clean battery contacts with a lint-free cloth to remove dirt or

grease.

Do not use solvents to clean your radio. Spirits may
permanently damage the radio housing.

!

Do not submerge the radio in the detergent solution.

Handling

• Do not pound, drop, or throw the radio. Never carry the radio by
the antenna.

• Avoid subjecting the radio to an excess of liquids.

• Avoid subjecting the radio to corrosives, solvents or spirits.

• Do not disassemble the radio.

• Keep the accessory-connector cover in place until ready to use
the connector. Replace the cover immediately once the accessory
has been disconnected.

Helpful Tips

Battery

Battery Life

Battery life is determined by several factors. Among the more critical
are the regular overcharge of batteries and the average depth of
discharge with each cycle. Typically, the greater the overcharge and
the deeper the average discharge, the fewer cycles a battery will last.
For example, a battery which is overcharged and discharges 100%
several times a day, will last fewer cycles than a battery that receives
less of an overcharge and is discharged to 50% per day. Further, a
battery which receives minimal overcharging and averages only 25%
discharge, will last even longer.

Charging the Battery

Motorola batteries are designed specifically to be used with a
Motorola charger and vice-versa. Charging in non-Motorola
equipment may lead to battery damage and void the battery warranty.
Motorola-authorized battery chargers may not charge batteries other
than the ones listed on page 43.

The battery should be at about 77°F (25°C) (room temperature),
whenever possible. Charging a cold battery (below 50° F [10°C]) may
result in leakage of electrolyte and ultimately in failure of the battery.
Charging a hot battery (above 95°F [35°C]) results in reduced
discharge capacity, affecting the performance of the radio. Motorola
rapid-rate battery chargers contain a temperature-sensing circuit to
ensure that batteries are charged within the temperature limits stated
above.

Battery Charge Status

Your radio can indicate your battery’s charge status via LED
indications and sounds:

• you see the LED flash red when the PTT button is pressed,
indicating low battery

• you hear a low-battery “chirp” (short, high-pitched tone)

Helpful Tips

Battery Recycling and Disposal

Nickel-cadmium (NiCd) rechargeable batteries can be recycled.
However, recycling facilities may not be available in all areas. Under
various U.S. state laws and the laws of several other countries, NiCd
batteries must be recycled and cannot be disposed of in landfills or
incinerators. Contact your local waste management agency for
specific requirements and information in your area.

Motorola fully endorses and encourages the recycling of NiCd
batteries. In the U.S. and Canada, Motorola participates in the
nationwide Rechargeable Battery Recycling Corporation (RBRC)
program for NiCd battery collection and recycling. Many retailers and
dealers participate in this program.

For the location of the drop-off facility closest to you, access RBRC's
Internet web site at www.rbrc.com or call 1-800-8-BATTERY. This
internet site and telephone number also provide other useful
information concerning recycling options for consumers, businesses,
and governmental agencies.
