WARNING
The cathode ray tube (CRT) may retain a dangerous electrical
(16 kV) charge. To prevent electric shock, fully discharge the anode
before removing the CRT. Short the anode lead from the CRT to the
chassis. Wait approximately ten minutes and again firmly short the
anode lead to the chassis. Then, remove the CRT.
If the CRT breaks, the glass fragments scatter at a high velocity
(implosion). Use extreme care when handling the CRT. Protective
clothing and safety glasses should be worn. Avoid striking the CRT
on any object which might cause it to crack or implode. When
storing a CRT, place it in a protective carton or set the CRT face
down in a protected location with a smooth surface and with the
CRT faceplate on a soft mat.
