<Fast Rate>
Operates
normally
Under <High
Speed>
Over <Low Speed>
(Only when the set
<High Speed>
<Low Speed>)
The interval is
calculated using the
following formula:
(Transmission Interval
= <Fast Rate> x
<High Speed> ÷
Speed)
Operates
normally
Below the <Low
Speed>
<Slow Rate>
Will not
operate
Transmission Interval Example:
(with <Low Speed> = 5, <High Speed> = 70, <Slow Rate>
= 30 min, <Fast Rate> = 120 sec)
Speed Interval
80 120 seconds (2 minutes)
70 120 seconds (2 minutes)
50 168 seconds (2 minutes 48 seconds)
30 280 seconds (4 minutes 40 seconds)
20 420 seconds (7 minutes)
10 840 seconds (14 minutes)
5 1680 seconds (28 minutes)
0 1800 seconds (30 minutes)

but is now used worldwide.
1 Set the <Type> to “New-N”, then press [MHz].
2 Set WIDE 1-1 to “Off” or “On”.
• Set <Wide 1-1> to “On” to use the digipeater of the Fill-in
type (RELAY type) with <New-N>.
• When set to “On”, 1 packet path in addition to <Wide 1-1>
can be used, as per the <Total Hops> setting.
3 Select the relay step number for the <Total Hops>
setting.
