Low Speed <Low Speed; High Speed <High Speed; Slow Rate <Slow Rate; Fast Rate <Fast Rate - Kenwood TM-D710E Instruction Manual

SETTING SmartBeaconing
Enter Menu mode and access Menu 630 and 631.
Set to use [SmartBeaconing] (Menu No.611) with APRS
data transmission.
This function optimizes beacon transmission based on
driving direction and speed. Use this function when you
want to track your transmissions, especially for optimizing
crossover beacon transmission intervals.
■ Low speed <LOW SPEED>
Low speed setting (2 ~ 30 <mi/h, km/h or knots>).
When the speed is lower than this, beacons are
transmitted at the time interval specified under SLOW
RATE.
Note: To select the speed setting of the units, access Menu 626
(DISPLAY UNIT 1 - SPEED, DISTANCE).
■ High speed <HIGH SPEED>
High speed setting (2 ~90 <mi/h, km/h or knots>).
When the speed is faster than this, beacons are
transmitted at the time interval specified under FAST
RATE.)
Note: To select the speed setting of the units, access Menu 626
(DISPLAY UNIT 1 - SPEED, DISTANCE).
■ Slow rate <SLOW RATE>
Low speed transmission interval time
(1 ~ 100 minutes).
■ Fast rate <FAST RATE>
High speed transmission interval time
(10 ~ 180 seconds).
■ Turn angle <TURN ANGLE>
Driving direction change, minimum value setting
(5 ~ 90 degrees).
■ Turn slope <TURN SLOPE>
Driving direction change, additional value setting
(1 ~ 255 (10degrees/speed)).
■ Turn time <TURN TIME>
Minimum time delay between each beacon
transmission by change of direction. (5 ~ 180 seconds).
Note:
◆ When Menu No. 602 is set to a value other than [GPS], it
operates at the SLOW RATE.
◆ Adjust the Setting values to match the actual driving status.

(with LOW SPEED = 5, HIGH SPEED = 70, SLOW RATE
= 30 min, FAST RATE = 120 sec)
Speed
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)
Corner Pegging Operation Example:
(with TURN ANGLE = 30°, TURN SLOPE = 24)

• When the value of [Turn Threshold] exceeds 120º, it is
calculated as 120º.
