Standing up to the challenge
Imagine this scenario – The shrill scream of the fire
alarm pierced the night. Within minutes, nine men
assembled outside a fire engine awaiting
“This is no ordinary fire,” cautioned the fire chief.
“We are dealing with a burning manufacturing
plant, and its storage area contains tanks which
may explode if burned, so please make sure you
are carrying the correct communications
equipment today.” The fire fighters checked their
Motorola GP628 Plus radios briefly, noting the
prominent green dot on the Li-ion battery pack,
which identifies it as an FM-rated battery.
As they arrived at the fire scene, its extent became
clear. Burning goods crackled noisily amongst the
shouts of frightened plant workers. Hearing one
another was going to be difficult.
The fire chief pulled on his helmet, oxygen tank
and protective gloves. He was thankful for the
lightweight radios– it was important not to burden
his men any more than necessary. Easily finding
the sculpted Push-to-Talk (PTT) button even with
his gloved hands, he addressed his men.
“Fan out into 3 teams. Team Alpha, go around the
back to make sure the fire does not spread to the
chemicals warehouse. Team Beta, control the fire
in front and around the sides. Team Charlie, follow
me inside for rescue operations. Over and out,”
the fire chief spoke calmly into his radio. He knew
he did not need to shout to make himself heard,
given the audio clarity from the GP628 Plus radio.
Visibility rapidly deteriorated once they were inside
the burning building. Out of the corner of his eye,
the fire chief sensed something looming over him.
“Collapse!” he shouted, as he and his men dived
away just a split second before a 20-foot wall
crumbled before them.
Picking up his axe, he searched around for his
radio, and found it lying in a pool of muddy water.
This did not bother him one bit – he knew the
GP628 Plus was IP67-rated water submersible,
thanks to its ruggedised casing. Moreover, the
IP67-rated dust-tight and water submersible radio
is designed and built to globally-recognised FM and
MIL standards.
A Rugged Radio for Harsh
Introducing the Motorola GP628 Plus non-keypad
and the GP638 Plus keypad radios, the toughest
from Motorola to date. Rated IP67 dust-tight and
water submersible, the radios are also resistant to
knocks and drops, thanks to their ruggedised
exteriors. The GP628 Plus and the GP638 Plus
feel right at home in the dangerous, extreme
world of emergency rescue operations.
Lightweight and compact, Motorola’s smallest
professional two-way radios have received Factory
Mutual (FM) Approval and meet Military Standards
(MIL) 810C, D, E and F.

Fire Rescue Operations
The Motorola GP628 Plus and GP638 Plus are
lightweight and compact and will not hamper you
during rescue operations. Durability is ensured with
IP67-rated protection against dust and water. Simple,
programmable buttons enable lightning-fast
communications during tense situations. A specially
sculpted ergonomic PTT button, similarly IP67-rated,
ensures easy operation even with gloved hands.
The rugged exterior of the GP628 Plus and GP638
Plus conform to stringent Factory Mutual (FM) and
Military Standards 810C, D, E and F, making them
suitable for operation in potentially sensitive
environments such as petrochemical and
manufacturing plants. The radios have been
subjected to Motorola Accelerated Life Testing (ALT)
which ensures that they can withstand drop/shocks,
rain, salt, fog, electro-static discharge and flame.
Rescue Operations
The IP67-rated GP628 Plus and GP638 Plus are
suitable for use in typhoons, earthquakes and flood
relief operations. Rescue personnel already burdened
with heavy equipment and protective gear will
appreciate the compact size, light weight and
ergonomic design of the radios.
IP Code
The IP Code is a designation that indicates the level or amount of protection.
The IP Code designation consists of the letters IP (International Protection) followed
by two numerals
Degree of protection against the
ingress of solid foreign objects.
6 = Dust-tight
Degree of protection against the
ingress of water with harmful
7 = Protection against the effects
of temporary immersion in water
(1m submersion for 30 minutes)
1m submersion for 30 mins
GP628 Plus and GP638 Plus Key
Features and Benefits
Dust-tight, water submersible, lightweight
and rugged
Advanced Audio Technology
Motorolas voice compression and low level
expansion technology enable crisp, clear and loud
audio, allowing you to keep communicating during
critical operations.
Emergency Alarm / Siren
An easily-accessible, one-touch emergency button on
the GP628 Plus or the GP638 Plus will emit a piercing
alarm when pressed, for urgent communications in
critical situations.
Switchable RF Power Levels
Adjusts the radios transmitting power according to
the user environment, and offers a choice between
maximum coverage and battery conservation. High
RF power increases transmission range, while low
power conserves battery life.
Repeater / Talkaround Enable / Disable
Enjoy long-range communications via a repeater, or
bypass it to communicate point-to-point. The
talkaround feature is useful for maintaining
communications lines when a repeater goes out of
Tight / Normal Squelch
Enhanced audio clarity is achieved by filtering out
unwanted interference. A tight squelch gives clearer
playback of messages, while a normal squelch
increases coverage.
Other Features
LED Battery Gauge
Tone Tagging
Internal VOX
Priority Scan
Enhanced Signalling Systems
GP628 Plus Compact & Easy to Use
Palm-sized and easy-to-use, any emergency-response team or fleet will be able
to familiarise themselves quickly with the GP628 Plus. Its intuitive layout and
programmable buttons offer fast responsiveness in emergency situations.
Time saved equals lives saved.
16 Channels
Assign up to 16 channels for easy organisation of different work groups.
LED Battery Gauge
An easily visible tri-colour battery gauge at the top of the radio provides battery
level status at a glance. Green indicates a full battery; amber means half-full
and red is a signal to recharge the battery.
Tone Tagging
Allows assignment of 8 different ring tones to 8 specific users or talkgroups,
for audio identification of these groups.
Enhanced Signalling Features of GP628 Plus
GP628 Plus supports the following systems:
MDC1200 Signalling
PTT-ID (encode) Identifies your outgoing calls during transmission, so
verbal identification is not necessary
Selective Call (decode) Allows you to receive a specific group or individual
Call Alert (decode) Notifies you of incoming calls
Radio Check (decode) Informs other workgroups that your radio is
activated or within range
Selective Radio Inhibit (decode) If the radio is missing or stolen, the system
owner can disable it remotely
Quick Call II Signalling
DTMF Signalling
