H200 Handset Guide DRAFT Proprietary and Confidential Page | 1 Handset Operations Manual H200 Technical Reference Document Version 1 © Jan-2026 RTX A/S, Denmark H200 Handset Guide DRAFT Proprietary and Confidential Page | 5 1 About This Document This document describes the features and functionalities available in the RTX SME VoIP DECT H200 Handset. We describe how to operate the handset without going into details of its mechanical features. The reference for features and operation in this manual is RTX generic mode. 1.1 Audience This guide is intended for everyday users as well as system administrators. 1.2 Abbreviations For the purpose of this document, the following abbreviations hold: DECT: Digital Enhanced Cordless Telecommunications IPEI: International Portable Equipment Identity MAC: Media Access Control PBX: Private Branch Exchange 1.3 References/Related Documentations VoIP System Guide 1.4 Document History REVISION AUTHOR ISSUE DATE COMMENTS 1 LIP 30-01-2026 First draft 1.5 What is new What new features have been added. REVISION WHAT IS NEW 1 First draft, new document 2 Making Handset Ready In this chapter we briefly describe how to prepare the handset for use, install, and how to insert and charge new batteries. H200 Handset Guide DRAFT Proprietary and Confidential Page | 6 2.1 Package - Contents/Damage Inspection 2.1.1 Before Package Is Opened Examine the shipping package for evidence of physical damage or mishandling prior to opening. If there is proof of mishandling prior to opening, you must report it to the relevant support center of the regional representative or operator. 2.1.2 Contents of Package Make sure all relevant components are available in the package before proceeding to the next step. In principle, every shipped handset unit package/box contains the following items: • 1 x Handset unit • 1 x Battery cover • 1 x Handset belt clip • 1 x Charger • 1 x A/C Adaptor • 1 x Battery • 1 x plastic cover to replace the belt clip H200 Handset Guide DRAFT Proprietary and Confidential Page | 7 2.1.3 Damage Inspection The following is the recommended procedure for you to use for damage inspection: 1. Examine all relevant components for damage. 2. Make a “defective on arrival - DOA” report or RMA to the operator. Do not move the shipping carton until the operator has examined it. The operator/regional representative will initiate the necessary procedure to process this RMA. They will guide the network administrator on how to return the damaged package if necessary. 3. If no damage is found, then unwrap all the components and dispose of empty package/carton(s) in accordance with country specific environmental regulations. 2.2 Before Using the Phone The following are the precautions users should read before using the handset: 2.2.1 Installing the Battery 1. Never dispose a battery in fire, otherwise it will explode. It must be delivered to a recycling company. 2. Never replace the batteries in potentially explosive environments, e.g. close to inflammable liquids/gases. 3. ONLY use approved batteries and chargers from the vendor or operator. 4. Do not disassemble, customize, or short circuit the battery 2.2.2 Using the Charger Each handset is charged using a handset charger. The charger is a compact desktop unit designed to charge and automatically maintain the correct battery charge levels and voltage. The handset charger is powered by AC supply from 100-240VAC that supplies 5.0VDC at 1000mA. When charging the battery for the first time, it is necessary to leave the handset in the charger for at least 10 hours before the battery is fully charged, and the handset is ready for use. 2.2.3 Handset in the Charger For correct charging, ensure that the room temperature is between 0°C and 25°C / 32°F and 77°F. Do not place the handset in direct sunlight. The battery has a built-in heat sensor which will stop charging if the battery temperature is too high. If the handset is turned off when placed in charger, the handset turns on and shows (shortly) the charging message “The battery is charging”. After a while the display backlight first dim and then turns off (if demo mode is not enabled). There will be response for e.g. incoming calls. If the handset is turned on when placed in charger, the display shows (shortly) the charging message “The battery is charging”. After a while the display backlight first dim and then turns off if unless “Idle Screen Saver” is switched on. H200 Handset Guide DRAFT Proprietary and Confidential Page | 8 2.2.4 How to Open Back Cover 1. Open the belt lock and slide down the back-cover as shown on the image below 2. Remove Back Cover from Handset 2.2.5 How to Replace Battery Remove the back cover from the handset as showed in section 2.2.4 How to Open Back Cover above. Then remove the old battery and replace with a new one. Note: The old and unused batteries must be delivered to a recycling company. 2.2.6 Handset Serial and IPEI/IPUI Number The serial number and IPEI/IPUI number of each handset is found either on a label, which is placed behind the battery, or on the packaging label. First, lift off handset back cover and lift the battery and read the serial number. 3 Phone Overview This section contains an overview of the handset from the front and rear side. 3.1 Handset – Front View H200 Handset Guide DRAFT Proprietary and Confidential Page | 9 1.

For the radiated spurious emission below 30MHz, only the worst case (parallel) was recorded. 2. For the radiated spurious emission below 1GHz, When the test result of peak was less than the limit of QP/Average more than 6dB, just peak value were recorded. 3.
