Malha de Terra
não use objetos pontudos que possam causar danos a super-
fície da chupeta.
Não comprima a cobertura de borracha com muita força para
colocar a chupeta, pois pode causar danos a mesma durante
esta operação.
Não gire a chupeta com força, a´pos colocada, para não causar
danos a mesma.
COMO MANUSEAR A CHUPETA DO ANODO
Levante um lado da capa de borracha
na direção indicada pela seta .
Quando um lado do anodo estiver sepa-
rado do botão do anodo, basta puxar par-
ra o outro lado que o anoda se solta com-
platamente.
.
Use seu polegar puxe a capa de borracha
firmemente na direção indicada pela
seta .
CUIDADO:Pode restar alta tensão no CRT após desligar a alimentação. Para evitar risco de choque elétrico, descarregue o CRT antes
tentar remover a chupeta. Aterre o anodo na malha de terra em torno do CRT.
NOTE: Após removido o anodo, curto-circuite o anodo do tubo e a chupeta com a blindagem metálica do tubo.

PROCEDIMENTO DE REMOÇÃO
CUIDADO:
ANTES DE REMOVER A
CHUPETA DO ANODO:
Pode restar Alta Tensão no CRT após desligar
a alimentação. Para evitar risco de choque elétri-
co, descarregue o CRT antes de tentar remo-
ver a chupeta. Aterre o anodo na malha de terra
em torno do CRT.
