Local, State and Federal organizations, government bodies and their various departments, user organizations and military may use this device in the extended frequency range. This device will also be sold in non-US markets where use of the extended frequencies may be authorized. The applicant also requests that the grant note code “EF” be included on the grant of Equipment Authorization for FCC ID: Y9M-KA500E, to indicate extended frequencies. The applicant will notify the end users in the US that: 1. The device is to be programmed only for the frequencies allowed by the user’s radio station authorization. 2. It is a violation of FCC rules if the device operates on unauthorized frequencies. 3. This device uses extended frequencies and may contain functions that are not operational in US territories, except as noted in the filing. Sincerely, Printed name: Mauro Campidoglio Date: 26/06/2024

Additionally, if the equipment is capable of transmitting data, has transmitter output power greater than 500 mW, and has a channel bandwidth of more than 6.25 kHz, the equipment must be capable of supporting a minimum data rate of 4800 bits per second per 6.25 kHz of channel bandwidth.” The PMR digital transceiver/repeater model KA-500e is designed to work in dual mode analog and digital mode, for both voice and data service. In digital mode it works in standard DMR mode: it transmits 2 channels in 12.5 kHz of bandwidth, with a spectral efficiency of 6.25kHz of bandwidth per channel. The 2 channels can be both voice, or both data, or one voice and one data. The bitrate in DMR mode is 9.6kbps in any case. Sincerely, Printed name: Mauro Campidoglio Date: 26/06/2024
