iii) Speed and Weight Setting
[1] CW (MORSE)
RECEIVING SPEED
Receiving speed is automatically determined. Dots which are less than 20 msec may be regarded
as noise. However, when slow CW is received right after rather fast CW, 2 – 4 characters are re-
quired before synchronization is achieved.
 For the faster sync, in high speed
WEIGHT | SPEED →H
(Push) (and then push)
 For the faster sync, in low speed
WEIGHT | SPEED →L
When the receiving speed of signals suddenly diminishes to less than half, it will sometimes hap-
pen that 8 – 12 characters are read as E or T by mistake. However, correct reading will be ob-
tained with the continuation of the CW signals at the new rate.
TR NSMITTING SPEED
Transmitting speed is automatically set at the speed of about 50 characters per minute in the initial
state.*
(* Pushing POWER switch ON or [ RESET ] key makes the initial state.)
 For the speed change
WEIGHT | SPEED →Ø ~ ) | 9
There are ten speeds to be selected as shown in Table 3.
