The kinescope bulb encloses a high vacuum and. due to its large surface area, is subjected to considerable air pressure. For these
reasons, kinescopes must be handled with more care than ordinary receiving tubes.
I he large end of the kinescope bulb
particularly that part at the rim of the viewing surface—must not be struck, scratched or sub¬
jected to more than moderate pressure at any time.
In installation, if the tube sticks or fails to slip smoothly into its socket, or de¬
flecting yoke, investigate and remove the cause of the trouble.
Do not force the tube. Refer to the Receiver Installation section for de¬
tailed instructions on .kinescope installation.
All RCA kinescopes are shipped in special cartons and should be left in the cartons until
ready for installation in the receiver.
Keep the carton for possible future use.
