precautions should be observed:
2Aerial Input Impedance1. 14A2-X :When repairing the circuit, be sure not to increase the high voltage
VHF/UHF .......................................................................................to more than 23.5 kV (at beam 0 75 ohm Unbalanced?A) for the set.
Receiving System ...............................................................CCiR SECAM/P21A2-X:When repairing the cirAL B, G, D, K, Icuit, be sure not to increase the high voltage
NTSC 3.58/4.43 MHzto more than 26.5 kV (at beam 0 ?A) for the set.
2. 14A2-X : To keep the set in a normal operation, be sure to make it function on
22.0 kV ? 1.5 kV (at beam 800 ?A) in the case of the set. The set has

? VHF-Channels ...........................................E2 (48.25 MHz) thru E12 (224.25 MHz)
21A2-X : To keep the set in a normal operation, be sure to make it function on
C1 (49.75 MHz) thru C12 (216.25 MHz)
24.8 kV ? 1.5 kV (at beam 1,100 ?A) in the case of the set. The set has
