ETL Conforms to UL Standard for Safety for Audio, Video and Similar electronic apparatus – Safety Requirements UL 60065, Issue:2003/06/30 Ed:7 Rev:2007/12/11 Certified to CSA Standard for Safety for Audio, Video and Similar electronic apparatus – Safety Requirements CAN/ CSA-C22.2 No. 60065:03, Issued 2003/04/01 Ed:1 Amendment 1:2006 Intertek ETL Control number: 4002355 WARNING! Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: 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 instal- lation. 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 interfer- ence will not occur in a particular installation. If this equip- ment 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 inter- ference 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. DANGER! DO NOT USE the COMFORT DIGISYSTEM products if you have a PACEMAKER or other implanted device. The Comfort Digisystem products could cause the pacemaker or other implanted device to malfunction and cause serious injury or death. Receiver DT10 4 3) Overview - Receiver DT10 Push-button For toggling between different listening modes and activating pairing mode. Europlug For connecting to the audio shoe on a hearing instrument or to the socket on the Programmer DT05. To be able to use the Receiver DT10, check if — and how — the hearing instrument supports the use of a mini receiver: 1. The hearing instrument must be equipped with an audio shoe with a powered Europlug socket made for mini receiver use. This connects the Receiver DT10 to the hearing instrument and also supplies the DT10 with power from the hearing instrument’s battery. The received audio signal will then be transferred from the Receiver DT10 to the hearing instrument through the audio shoe. 2a. If the hearing instrument is equipped with a Programmable DAI input (DPAI), programming of the hearing instrument might be necessary (check with audiologist or hearing instrument manufacturer). In this case the push-button on the Receiver DT10 cannot switch between the R and R+M modes. This is instead done by using different listening programs in the hear- ing instrument. Europlug TIP! The volume of the Receiver DT10’s R and R+M mode can be set individually by using the Programmer DT05. This makes it possible to use the push-button as a simple volume control in combination with a hearing instrument with Programmable DAI input (DPAI). 4) Check the hearing instruments input 2) Introduction to the Comfort Digisystem Thank you for choosing Comfort Digis…

The DT05 use Binary (two-level) FSK modulation, operating at the fixed frequency of 904.05 MHz with a 6dB bandwidth greater than 500 KHz and use burst transmissions. The duty cycle of the transmissions is very low and can be compared to an ordinary RF-remote control where the duty cycle is depending on the operator. DT05 use an internal fixed antenna and the maximum output power (antenna gain included) is -25dBm. The system is used by professionals to configure the DT10 to meet customer’s specific requirements. The Programmer DT05 has an inbuilt Li-Ion polymer battery (nominal voltage of 3.7v). The battery is charged via a power supply, which is connected to the mains.
