2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network inter-
face.

4. Use caution when installing or modifying telephone lines.

INSTRUCTION FOR BATTERIES

CAUTION: To Reduce the Risk of Fire or Injury to Persons, Read and Follow these Instructions:

1. 

Use only the type and size of batteries mentioned in owner’s manual.

2. 

Do not dispose of the batteries in a fire. The cells may explode. Check with local codes for possible special disposal 

instructions.

3. 

Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or skin. It 

may be toxic if swallowed.

4. 

Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, 

and keys. The battery or conductor may overheat and cause burns.

5. 

Do not attempt to recharge the batteries provided with or identified for use with this product. The batteries may leak 

corrosive electrolyte or explode.

6. 

Do not attempt to rejuvenate the batteries provided with or identified for use with this product by heating them. Sudden 

release of the battery electrolyte may occur causing burns or irritation to eyes or skin.

7. 

When replacing batteries, all batteries should be replaced at the same time. Mixing fresh and discharged batteries 

could increase internal cell pressure and rupture the discharged batteries. (Applies to products employing more than one sepa-
rately replaceable primary battery.)

8. 

When inserting batteries into this product, the proper polarity or direction must be observed. Reverse insertion of bat-

teries can cause charging, and that may result in leakage or explosion. (Applies to product employing more than one separately 
replaceable primary battery.)

9. 

Remove the batteries from this product if the product will not be used for a long period of time (several months or more) 

since during this time the battery could leak in the product.

10. 

Discard “dead” batteries as soon as possible since “dead” batteries are more likely to leak in a product.

11. 

Do not store this product, or the batteries provided with or identified for use with this product, in high-temperature 

areas. Batteries that are stored in a freezer or refrigerator for the purpose of extending shelf life should be protected from con-
densation during storage and defrosting. Batteries should be stabilized at room temperature prior to use after cold storage.
