2.6 Charger Options The HT50 is supplied with a TC50 trickle charger that will accept the whole radio, or the battery only (Fig 2.5). The TC50 runs from a 12.6v-15.5v DC supply or from AC mains with an appropriate optional adaptor / power supply. Charging with the trickle charger takes approximately 12-16 hours. There is also a rapid charger available (RC50) which will charge the battery within 11/2 hours. 2.
2.8 Battery Level Indicator Except when adjusting the Volume or Squelch, the bar graph on the display shows the battery charge level (Fig 2.7). This indicates the voltage at the battery terminals, not necessarily the charge stored. Ten or nine bars indicate a fully charged battery, three or four bars mean the battery is almost drained. • A more accurate indication of the battery state will be obtained by transmitting briefly on high power. Do not use CH16 for this purpose.
3 Appendix 3.1 Licensing Prior to use check the national licensing requirements for the operator. In the UK license applications and queries should be made to the following authority Ship Radio Licensing Radio Licensing Centre The Post Office PO Box 1495 Bristol BS99 3QS A set may only be operated by, or under the supervision of a holder of a Certificate of Competence and Authority to Operate. This involves a simple examination and an annual license renewal fee.
3.2 Antenna The antenna for the radio is fitted to the unit via a robust screw fitting to an M6 threaded socket on the top of the radio. This system is more rugged than a traditional BNC connector, so the radio’s drop-proof integrity is not compromised by the antenna fixing. While the radio is drop-proof and very robust, damage to the antenna such as bending or kinking may adversely affect the transmission efficiency of the unit, which may lead to overloading of the power module.
3.4 Frequency of Channels Axis 50 GMDSS models are fitted with simplex channels only. Ch 70 is restricted for DSC (Digital Selective Calling) use only and is therefore not available on the HT50 or Axis 50 VHF radio. Ch 0 will only be made available in the UK to Coastguard users with written authorisation. Page 15 offerd by www.Busse-Yachtshop.de email: info@busse-yachtshop.
3.5 Battery Life Guidelines • New batteries should be fully (trickle) charged and fully discharged several times to achieve full capacity. To a large extent, the battery life will depend on the usage, or Duty Cycle of the radio - i.e the battery will be drained much quicker if the radio is transmitting continually than if it is just receiving.
3.6 Fault Finding Symptom Possible Cause Remedy Unit will not switch on • Battery not charged • Battery not attached correctly to radio • Re-charge battery • Ensure battery is fully engaged (see section 2.
