If a Signal Appears on the Selected Channel
Scanning	will	pause	on	the	selected	channel	BUT	Channel	
16	and	the	Priority	Channel	will	continue	to	be	monitored	
every	2	seconds.	During	this	time	the	PTT	may	be	
pressed	for	normal	transmissions	on	the	selected	channel	
(monitoring	of	Channel	16	and	the	Priority	Channel	ceases	
while	transmitting).	Once	the	selected	channel	has	become	
inactive	for	5	seconds	the	Triple	Watch	will	resume.
To Transmit on the Selected Channel While 
Triple Watching 
Simply	press	the	PTT.	The	Triple	Watch	function	will	pause	
during	the	transmission	and	remain	paused	until	5	seconds	
after	all	activity	has	ceased	on	the	channel.	Triple	Watch	will	
then	resume.
To Transmit on the Priority Channel While 
Triple Watching 
Briefly	press	the	CHAN A	key.	The	Priority	Channel	will	
then	become	the	selected	channel.	Now	press	the	PTT	and	
transmit	in	the	usual	way.	When	your	conversation	has	
ended,	re-select	your	selected	channel.	
To Transmit on Channel 16 While Triple Watching
Press	the	16	key.	Triple	watch	will	be	cancelled	and	the	
radio	will	switch	straight	to	Channel	16.	Now	press	the	
PTT	and	transmit	in	the	usual	way.	When	your	conversation	
has	ended,	press	and	hold	the	TW	key	to	resume	Triple	
Watching.
SCANNING
The	Scan	function	allows	the	GX600A	to	scan	through	
a	series	of	user	selected	channels	looking	for	activity.	
Scanning	is	done	in	an	ascending	sequence	at	a	rate	of	10	
channels	per	second.	
Channels	can	be	selected	and	stored	for	scanning	from	any	
of	the	available	channels,	including	weather	channels	(if	the	
USA	channel	set	is	selected)	and	private	channels	(if	they	
are	enabled).	
NOTE:
The transmitter is disabled while scanning. If the
PTT	is	pressed,	a	low	beep	will	be	heard	and	the	PTT	is	
ignored.
To Store Channels for Scanning
Select	the	required	channel	using	the	 	or	 	keys,	then	
press	and	hold	the	SCAN	key	for	1.5	seconds.	The	channel	
number	will	flash,	a	high	beep	with	be	heard	and	‘M’	will	
appear	next	to	the	channel	number.	
Repeat	the	process	to	remove	a	previously	stored	channel	
from	the	scan	list.	When	a	channel	is	removed	a	low	beep	is	
heard	and	‘M’	disappears	from	the	display	on	that	channel.
To Begin Scanning
Briefly	press	the	SCAN	key.	The	GX600A	will	scan	upwards	
through	the	stored	channels	at	10	channels	per	second	and	
the	display	will	show	rapidly	changing	channel	numbers.	
If	a	signal	is	located,	scanning	will	pause	on	that	channel	
and	will	remain	for	5	seconds	after	the	signal	has	gone.	
Scanning	will	then	resume.
To Stop the Scan
Briefly	press	the	SCAN	key	again.	The	radio	will	return	to	
the	last	selected	channel.
SCANNING FEATURES
If the Scan is Paused on a Busy Channel and you 
Wish to Remain on That Channel 
Briefly	press	the	SCAN	key.	Scanning	will	be	cancelled	and	
the	radio	will	remain	on	that	channel.	To	resume	scanning,	
briefly	press	the	SCAN key	again.
If the Scan is Paused on a Busy Channel and you 
Wish to Skip over that Channel 
Briefly	press	the	 	or	 	key.	Scanning	will	resume	with	the	
next	channel	in	sequence.	As	an	alternative,	pressing	the	
SCAN	key	twice	will	give	the	same	result.
If the Scan is Paused on a Busy Channel and you 
Wish to Transmit on that Channel 
Simply	press	the	PTT	switch.	Scanning	will	be	cancelled	and	
the	radio	will	remain	on	that	channel.	Note,	if	the	PTT	is	
pressed	at	any	other	time	while	scanning,	a	low	beep	will	
be	heard	and	the	PTT	will	be	ignored.
To Switch Immediately to Channel 16
Briefly	press	the	16	key.	Channel	16	will	be	selected,	
scanning	will	be	cancelled	and	the	radio	will	be	restored	to	
normal	operation	with	high	transmitter	power	selected.
To Switch Immediately to a Stored Working 
Channel (CHAN A or CHAN B) 
Briefly	press	the	CHAN A	or	CHAN B	key.	Scanning	will	be	
cancelled	and	the	radio	will	switch	to	the	channel	stored	in	
the	selected	memory.
Scanning Notes
1. Each channel set has its own independent scan memory.
E.g.	Scan	channels	stored	under	the	International	channel	
do	not	affect	those	stored	under	the	USA	channel	set.	
2. If the GX600A is switched off while it is scanning, it
will	resume	scanning	automatically	when	it	is	switched	
ON	again.
