2-24. OPERATION UNDER UNUSUAL CONDITIONS.
COLD CLIMATES
Keep the telegraph terminal warm and dry. Operate the equipment continuously, if possible. Tube
filaments will furnish some heat.
When the equipment has been exposed to low temperatures and then is brought into a warm room,
condensation will form on the inside and outside surfaces. Wait for condensation to dry before
placing equipment in operation.
HOT DRY CLIMATES
Protect the telegraph terminal from sand, dust, and strong sunlight. Clean and dust the outside
surfaces often.
Whenever installation permits, keep equipment in its case to protect components from sand and
dust.
WARM, DAMP Climates
Protect equipment from humidity and fungus.
Remove moisture and fungus from outside surfaces with lint free cloth.
