DTP-800/DTP-1900 Operating Manual 1 1. Introduction Thank you for purchasing this product. Please check whether the product package contains the following items. If there are missing items, please call the service center. 1. Phone 2. Power Supply(SMPS) 3. Antenna 4. Installation Panel 5. User’s Manual 6. Power Cord 7. Screws DTP-800/DTP-1900 Operating Manual 2 1.1 Installation Procedure Connect the DC jack to the back panel of phone as shown in the figure below. Connect the plug of the SMPS to a power outlet and to SMPS for the phone. Turn power on by moving the switch button to the right as shown following figure, and then the phone is initialized with power-up sound. DTP-800/DTP-1900 Operating Manual 3 Adjust the antenna direction until the maximum Antenna power sign is displayed on the LCD screen. (Each bar indicates the received signal strength. The more bars mean the higher signal strength, the better service condition.) See 2.1 Power-Up / Power-Down 1.2 Installation of the Wall Bracket Before finalizing the precise location of the phone, please perform the signal strength test to find the best location after the unit is assembled. In case of the concrete wall, make 3mm holes with a drill at the marked location and attach the Installation Panel. When install mounting screws, do not screw in all the way. Leave 2mm space between the screw head and the installed panel. On the bottom of the phone, please find the wall mounting slots(A1 ~A4). Install A1 and A2 onto the top screws. And then push the wall mounting slots A3 and A4 onto the bottom screws so that the phone is finally seated.

DTP-800/DTP-1900 Operating Manual 7 2. Before Using 2.1 Power-Up / Power-Down 2.1.1 General Power-Up Manufacturer’s logo will be displayed for 1 second when the power is turned on. The screen (figure 2.1.1-2) will be displayed with the power-up sound. f the phone receives the signal from the Service Provider, the screen displays the default date and time set by factory. (figure 2.1.1-3) 11:11 am Nov 11 (Sun) DOWTEL WIRELESS PHONE DTP-800/DTP-1900 Operating Manual 8 2.1.2 No Service If “No Service” message is appeared like the figure 2.1.2, the location where the phone is installed may be the area of which the signal from the Service Provider is not delivered to the phone. If the number of bar beside the Ant. symbol on the screen in figure 2,1,1- 3 is small, it means the received signal strength is weak. < Reference 2.3.1 RSSI Icon> In this case, adjust the direction of antenna until the number of bar is displayed as many as possible. If the condition like figure 2.1.2 is continued or the number of bar is small despite of changing the direction of antenna, please ask the service center. 2.1.3 Registration Required If “Registration Required” message is appeared like figure 2.1.3, it means this phone cannot be registered to the Service Provider. In this case, report to the Service Provider immediately. No Service Required Registration DTP-800/DTP-1900 Operating Manual 9 2.1.4 Power Two types power is used in this phone. - AC power : 100 ~ 270 V - Internal Battery If the AC power is suddenly disconnected to the phone by a power failure or any reason, the power source is automatically changed from AC power to internal battery. When the status of power switch of the phone is turned on, the phone normally works as long as you disconnect the AC power. If you don’t want the power entirely, you must turn off the power switch.
