INFORMATION

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment. If you have any questions about this product, you may call: Sony Customer Information Services Center 1-800-222-7669 or http://www.sony.com/

Press xSTOP. The unit stops at the beginning of the current recording.
1 Press DISPLAY/MENU for more than 1 second until MODE appears in the display window. The unit enters the menu mode.
To record in better sound quality, select the HQ mode. For switching the recording mode, see Changing the Recording Mode on the reverse side. Before making a long recording, be sure to check the battery indicator. The maximum recording time and the number of messages you can make vary depending on the conditions of use. When you record messages in the mixture of HQ, SP and LP mode, the maximum recording time will be between those for the HQ and LP modes. Due to the limitation of the IC recording system, this unit records in the minimum recording unit of approx. 2 seconds at most, therefore the following symptoms may occur: When a message is shorter than the minimum recording unit, it is still counted as approx. 2 seconds at most so the remaining recording time will decrease by more than the actual length of the message. When the message is longer than the minimum recording unit, the remaining recording time will decrease by more than the actual length of the message if it cannot be divided by the minimum recording unit without a remainder. The sum of the number on the counter (elapsed recording time) and the remaining recording time may be less than the units maximum recording time.
